Abstract

Disclosed is a process for growing the microflora Thraustochytrium, Schizochytrium and mixtures thereof, which includes the growing of the microflora in fermentation medium containing non-chloride containing sodium salts, in particular sodium sulfate.
In a preferred embodiment of the present invention, the process produces microflora having a cell aggregate size useful for the production of food products for use in aquaculture. Further disclosed is a food product which includes Thraustochytrium, Schizochytrium, and mixtures thereof, and a component selected from flaxseed, rapeseed, soybean and avocado meal. Such a food product includes a balance of long chain and short chain omega-3 highly unsaturated fatty acids.

Description

PROCESS FOR GROWING THRAUSTOCHYTRIALES
Field of the Invention The field of this invention relates to heterotrophic organisms and a process for culturing them for the production of lipids with high concentrations of omega-3 highly unsaturated fatty acids (HUFA) suitable for human and animal consumption as food additives or for use in pharmaceutical and industrial products.

Background of the Invention Omega-3 highly unsaturated fatty acids (HUFAs) are of significant commercial interest in that they have been recently recognized as important dietary compounds for preventing arteriosclerosis and coronary heart disease, for alleviating inflammatory conditions and for retarding the growth of tumor cells. These beneficial effects are a result both of omega-3 HUFAs causing competitive inhibition of compounds produced from omega-6 fatty acids, and from beneficial compounds produced directly from the omega-3 HUFAs themselves (Simopoulos et al., 1986). Omega-6 fatty acids are the predominant HUFAs found in plants and animals.

Currently, a commercially available dietary source of omega-3 HUFA is from certain fish oils which can contain up to 20-30% of these fatty acids. The beneficial effects of these fatty acids can be obtained by eating fish several times a week or by daily intake of concentrated fish oil.

Consequently large quantities of fish oil are processed and {E6052653.DOC;1}
-2-encapsulated each year for sale as a dietary supplement. However, there are several significant problems with these fish oil supplements, including bioaccumulation of fat-soluble vitamins and high levels of saturated and omega-6 fatty acids, both of which can have deleterious health effects.
Another source of omega-3 HUFAS is the microflora Thraustochytrium and Schizochytrium which are discussed in detail in related U.S. Patent No.
5,130,242. These microflora have the advantages of being heterotrophic and capable of high levels of omega-3 HUFA production. There still exists a need however for improved methods for fermentation of these microflora and identification of improved uses of the microflora product.

Brief Summary of the Invention The present invention is directed to a new process for growing the microflora Thraustochytrium, Schizochytrium, and mixtures thereof, which includes the growing of the microflora in a culture medium containing non-chloride containing sodium salts, preferably including sodium sulfate. More particularly, a significant portion of the sodium requirements of the fermentation are supplied as a non-chloride containing sodium salt. The present process is particularly useful in commercial production because the chloride content in the medium can be significantly reduced, thereby avoiding the corrosive effects of chloride on fermentation equipment. In addition, the present invention {E5009987.DOC;1)
-3-is particularly useful for production of food products for use in aquaculture because Thraustochytrium and Schizochytrium cultured in such media form much smaller clumps than those cultured in high chloride media and are thus more available as a food source for larval shrimp. In particular, Thraustochytrium and Schizochytrium cultured in medium containing sodium sulfate can have cell aggregates of an average size of less than about 150 microns in diameter.

A further embodiment of the present invention is the production of a microflora biomass comprising Thraustochytrium, Schizochytrium, and mixtures thereof which have an average cell aggregate size of less than about 150 microns. The microflora biomass is useful for aquaculture and in particular, for feeding larval shrimp because the microflora have the primary feed advantages required for shrimp of a high sterol content and a high omega-3 highly unsaturated fatty acid (HUFA) content. Additionally, because of the small cell aggregate size, the microflora can be eaten by the larval shrimp, brine shrimp, rotifers, and mollusks.
The present invention further includes a process for the production of these organisms which includes feeding Thraustochytrium, Schizochytrium, and mixtures thereof, having an average cell size of less than about 150 microns to them.

A further embodiment of the present invention is directed to a food product which is comprised of microflora selected from the group consisting of Thraustochytrium,
4 -Schizochytrium, and mixtures thereof and an additional component selected from the group consisting of flaxseed, rapeseed, soybean, avocado meal, and mixtures thereof. A

particular advantage of this food product is that it has a high long chain omega-3 fatty acid content and a high short chain omega-3 fatty chain content from the additional component. In a further embodiment, the food product is produced by extrusion. The extrusion process involves mixing the microflora with the additional component, thereby reducing the moisture content of the food product. The food product is then extruded under heat, thus driving off a significant portion of the reduced moisture. The remaining amount of the original moisture content is readily removed by air drying or short baking times, thereby reducing the overall energy requirements of drying and the potential degradation of the omega-3 HUFA's by extended drying at high temperatures.

In one embodiment, the invention is concerned with a process for growing microflora from the order Thraustochytriales, comprising growing said microflora in a culture medium containing less than 3 grams of chloride per liter of said culture medium, sources of carbon, nitrogen, micronutrients, and a non-chloride sodium salt at a temperature from 5 C to 48 C and at a pH from pH 5.0 to pH 11.0, wherein the concentration of said sodium, {E5010805.DOC;1}

- 4a -expressed as grams of sodium per liter of said culture medium, is between 2 g/l and 25 g/l.
In another embodiment, the invention is concerned with a process of growing Thraustochytriales, comprising growing said Thraustochytriales in a culture medium containing a non-chloride sodium salt, sources of carbon, nitrogen, and micronutrients, and having less than 3 grams of chloride per liter of said culture medium, and wherein less than 50% of the sodium in the fermentation medium is supplied as sodium chloride.
In a another embodiment, the invention is concerned with a process for growing microflora from the order Thraustochytriales, comprising growing said microflora in a culture medium containing less than 120 milligrams of chloride per liter of said culture medium, sources of carbon, nitrogen, micronutrients, and a non-chloride sodium salt at a temperature from 5 C to 48 C and at a pH from pH 5.0 to pH
11Ø
In another embodiment, the invention is concerned with a biomass selected from the order Thraustochytriales, wherein the microflora is produced by any of the processes described herein.

Detailed Description of the Preferred Embodiments For purposes of definition throughout the application, it is understood herein that a fatty acid is an aliphatic ?-monocarboxylic acid. Lipids are understood to be fats or oils including the glyceride esters of fatty acids along with associated phosphatides, sterols, alcohols, hydrocarbons, ketones, and related compounds.

A commonly employed shorthand system is used in this specification to denote the structure of the fatty acids (e.g., Weete, "Far-ty Acids",pp. 49 - 95, 1980, in Lipid 8 :chemistry of Fungi and Other Organisms (Plenum Press. This system uses the letter "C,, accompanied by a number ckerjot:ing she number of carbons in accompanied by a number denoting the number of carbons in the hydrocarbon chain, followed icy a colon and a number indicating the number of double bonds, i.e., C20:5, eicosapentaenoic acid. Fatty acids are numbered starting at the carboxy carbon. Position of the double bonds is indicated by adding the Greek letter delta (d) followed by the carbon number of the double bond; i.e., C20:5omega-3L15.8.11.14,17. The "omega" notation is a shorthand system for unsaturated fatty acids whereby numbering from the carboxy-terminal carbon is used. For convenience, n-3 will be used to symbolize "or.ega-3, n especially when using the numerical shorthand nomenclature described herein. omega-3 highly unsaturated fatty acids are understood to be polyethylenic fatty acids in which the ultimate ethylenic bond is 3 carbons from and including the terminal methyl group of the fatty acid. Thus, the complete nomenclature for sieosapentaenoic acid, an omega-3 highly unsaturated fatty acid, would be C20:5n-3&5.8.11.14.17. For the sake of brevity, the double bond locations will be omitted. Eicosapentaenoic acid is then designated C20;5:.-3, nocosapentaenoic acid (C22: 5n--3A7.10.13.16.19) is C22:5n-3, and Aocosahexaenoic acid (C22:6n-3 A4,7,10,13,16,19 is C22:5n-3. The nomenclature "highly unsaturated fatty acid" means a fatty acid with 4 or more double bonds. "Unsatux'ated fatty aci(j" means a tatty acid with 1 to 3 double bonds-A collection and screening process has been developed to readily isolate many strains of microorganisms with the following combination of economically desirable character-istics for the production of omega-3 HUFAs_ 1) capable of heterot_ophic growth; 2) high content of omega-3 HOFAs; 3) unicellular; 4) preferably low content of saturated and omega-6 HUFAs; 5) preferably nonpigmented, white or essentially colorless cells; 6) preferably thermotolerant (ability to grow at temperatures above 30 C); and 7) preferably euryhaline (able to grow over a wide range of salinities, but especially at low salinities). This process is described in detail in related U.S. Patent No. 5,130,242.
Using the collection and screening process, strains of unicellular microflora can be isolated which have fatty acid contents up to about 45% total cellular dry weight percent (%dwt), and which exhibit growth over a temperature range from 15-48 c and grow in a very low salinity culture medium.
Many of the very high omega-3 strains are very slow growers.
Strains which have been isolated by the method outlined above, and which exhibit rapid growth, good production and high omega-3 HUFA content, have omega-3 unsaturated fatty acid contents up to approximately 12% dwt.

one aspect of the present invention is the growth of Thraustoehytriuw, Schizochytrlum, and mixtures thereof with 214.623
7 PCT/US93/09679 high omega-3 HUFA content, in fermentation medium containing non-chloride containing sodium salts and preferably sodium sulfate. More particularly, a significant portion of the sodium requirements of the fermentation are supplied as non-chloride containing sodium salts. For example, less than about 75% of the sodium in the fermentation medium is supplied as sodium chloride, more preferably less than about 50% and more preferably less than about 25%. A particular advantage of the present invention is that the medium provides the source of sodium needed by the microflora to grow in the absence of a significant amount of chloride which can corrode the vessel in which the microflora are being grown and other fermentation or downstream processing equipment. It has been surprisingly found that microflora of the present invention can be grown at chloride concen-trations of less than about 3 gl/l, more preferably less than about 500 mg/l, more preferably less than about 250 mg/l and more preferably between about 60 mg/l and about 120 mg/l while still attaining high yields of biomass per sugar of about 50% or greater. As discussed below, an additional advantage of the present invention is the production of microflora that are high in omega-3 HUFA content but have a small enough cell aggregate size to be consumed by larval shrimp, brine shrimp, rotifers and mollusks.

Non-chloride containing sodium salts can include soda ash (a mixture of sodium carbonate and sodium oxide) , sodium carbonate, sodium bicarbonate, sodium sulfate and mixtures thereof, and preferably include sodium sulfate. Soda ash, sodium carbonate and sodium bicarbonate tend to increase the pH of the fermentation medium, thus requiring control steps to maintain the proper pH of the medium. The concentration of sodium sulfate is effective to meet the salinity require-ments of the microflora, preferably the sodium concentration is (expressed as g/l of Na) is greater than about 1.0 g/l, more preferably between about 1.0 g/l and about 50.0 g/l and more preferably between about 2.0 g/l and about 25 g/l.

It has been surprisingly found that fermentation of the strains in the presence of a non-chloride containing sodium salt and particularly, sodium sulfate limits the cell aggregate size of the strains to less than about 150 microns, preferably less than about 100 microns, and more preferably less than about 50 microns. As used herein, the term cell aggregate size refers to the approximate average diameter of clumps or aggregates of cells in a fermentation medium of a microfloral culture. Typically, greater than about 25 percent of the cell aggregates in a microfloral culture have cell aggregate size below the average size, more preferably greater than about 50 percent and more preferably greater than about 75 percent. Microfloral cells produced in accordance with the present invention meet cell aggregate size parameters described above while in fermentation medium as well as after freezing and/or drying of the biomass if resuspended in liquid or physically agitated, such as by a blender or vortexer. The present process is particularly important for microflora which replicate by successive bipartition (wherein a single cell replicates by dividing into two cells which each divide into two more, etc.) because as cells repeatedly and rapidly undergo this process, the cells tend to clump forming multi-cell aggregates which are often outside the cell a.=gregate size parameters identified above. Schizochytrium replicate by successive bipartition and by forming sporangia which release zoospores.
Thraustochytrium, however, replicate only by forming sporangia and releasing zoospores. For Thraustochytrium which replicate by sporangia/zoospore formation, clumping can be a problem as well, particularly because even though the number of cells in an aggregate may not be as great as aggregates formed by successive bipartition, the individual cell sizes of Thraustochytrium tend to be larger, and thus, clumps of a small number of cells are larger. However, one deposited strain of Thraustochytrium, ATCC 26185, has been identified which does not exhibit significant aggregation.
In another aspect of the present invention, it has been found that by restricting the oxygen content of the fermentation medium during the growth of Thraustochytrium, Schizochytrium, and mixtures thereof, the lipid content of the strains can be increased. The optimum oxygen concentration for lipid production can be determined for any particular microflora by variation of the oxygen content of the medium. In particular, the oxygen content of the fermentation medium is maintained at an oxygen content of less than about 40% of saturation and preferably between about 5% of saturation and about 40% of saturation.

Growth of the strains by the invention process can be effected at any temperature conducive to satisfactory growth of the strains; for example, between about 5 C and about 48 C, preferably between about 15'C and about 40 C, and more preferably between about 25 C and about 35 C. The culture medium typically becomes more alkaline during the fermentation if pH is not controlled by acid addition or buffers. The strains will grow over a pH range from 5.0-11.0 with a preferable range of about 6.0-8.5.

Various fermentation parameters for inoculating, growing and recovering microflora are discussed in detail in U.S.
Patent No. 5,130,242. The biomass harvested from a fermentation run can be dried (e.g., spray drying, tunnel drying, vacuum drying, or a similar process) and used as a feed or food supplement for any animal whose meat or products are consumed by humans. Similarly, extracted omega-3 HUFAs can be used as a feed or food supplement. Alternatively, the harvested and washed biomass can be used directly (without drying) as a feed supplement. To extend its shelf life, the wet biomass can be acidified (approximate pH = 3.5-4.5) and/or pasteurized or flash heated to inactivate enzymes and then canned, bottled or packaged under a vacuum or non-oxidizing atmosphere (e.g., N2 or Coe) . The term "animal means any organism belonging to the kingdom Animalia and includes, without limitation, any animal from which poultry meat, seafood, beef, pork or lamb is derived. Seafood is derived from, without limitation, fish, shrimp and shellfish.
The term "products" includes any product other than meat WO 94/08467 2.1 4 6 2 3 PCT/US93/09679 derived from such animals, including, without limitation, eggs or other products. When fed to such animals, omega-3 HUFAs in the harvested biomass or extracted omega-3 HUFAs are incorporated into the flesh, eggs or other products of such animals to increase the omega-3 HUFA content thereof.
A further embodiment of the present invention is the use of the harvested biomass as a food product for larval shrimp, brine shrimp, rotifers and mollusks and in particular, larval shrimp. During the larval stage of development, shrimp larvae are unable to use some food sources because the food source is too large. In particular, at certain stages of development, shrimp larvae are unable to use a food source having a diameter greater than about 150 microns. Thus, microflora grown in fermentation medium containing a non-chloride sodium salt, and particularly sodium sulfate, as broadly discussed above, are suitable for use as a shrimp food product. As discussed above, microflora grown under such conditions typically have a cell aggregate size less than about 150 microns, preferably less than about 100 microns, and more preferably less than about 50 microns.
A further advantage of the use of microflora of the present invention as a food source for shrimp is that such microflora have a significant sterol content including cholesterol, which is a primary feed requirement for shrimp.

The microflora of the present invention typically have a sterol content of preferably at least about 0.1% ash-free dry weight (afdw) , more preferably at least about 0.5% afdw, and even more preferably at least about 1.0% afdw. In addition, the microflora of the present invention typically have a cholesterol content of preferably at least about 15%
of the total sterol content, more preferably at least about 25% of the total sterol content, and even more preferably at least about 40% of the total sterol content. Further, the microfloral biomass of the present invention also provide shrimp with additional nutritional requirements such as omega-6 fatty acids, protein, carbohydrates, pigments and vitamins.

The microbial product of the present invention is of value as a source of omega-3 HUFAs for fish, shrimp and other products produced by aquaculture. The product can be used as a food product as described above for shrimp; or added directly as a supplement to the feed for shrimp and fish, generally; or it can be fed to brine shrimp or other live feed organisms intended for consumption by an aquacultured organism. The use of such microflora in this manner enables the shrimp farmer to obtain significantly higher growth rates and/or survival rates for larval shrimp and to produce post-larval shrimp which are more hardy and robust.

For most feed applications, the fatty acid content of the harvested cells will be approximately 15-50% dwt with the remaining material being largely protein and carbo-hydrate. The protein can contribute significantly to the nutritional value of the cells as several of the strains that have been evaluated have all of the essential amino acids and would be considered a nutritionally balanced protein.

A further embodiment of the present invention is the production of a food product using the Thraustochytrium, Schizochytrium, and mixtures thereof, of the present invention, combined with an additional component selected from the group consisting of rapeseed, flaxseed, soybean and avocado meal. A particular advantage of this embodiment is that the food product contains both short chain omega-3 HUFAs from the additional component and long chain omega-3 HUFAs from the microflora. Food products having flaxseed, rapeseed, soybeans and avocado meal are known to be useful for supplying a source of short chain omega-3 HUFAs and for additionally supplying a source of short chain omega-3 HUFAs, which can be elongated by the humans and animals that ingest them. Such food products, however, have the disadvantages of having high choline contents from the additional component, which can form primary amines and result in an unpleasant fish smell; and toxic compounds from the additional component, which at high levels can, for example, inhibit the laying of eggs by hens or cause animals to go off of their feed. As such, the food product of the present invention has the advantage of a lowered flaxseed, rapeseed, soy bean or avocado meal content because the organism ingesting the food product does not need high levels of short chain omega-3 HUFAs for the purpose of converting them to long chain HUFAs. Thus, the lowered content of the flaxseed and rapeseed of the food product results in lowered amounts of choline and/or inhibitory toxic compounds present in the food product.

The amount of Thraustochytrium, Schizochytrium, and mixtures thereof, used in the food product can range from between about 5% to about 95% by weight. The additional component can be present in the food product at a range of between about 5% to about 95% by weight. Additionally, the food product can include other components as well, including grains, supplements, vitamins, binders and preservatives.

In a preferred embodiment, the above food product is produced using an extrusion process. The extrusion process involves mixing the microflora with the additional component, thereby reducing the moisture in the microfloral biomass by the amount of the additional component mixed. The food product is extruded under heat, thus removing further moisture from the food product. The resulting product which has a low moisture content can be air dried or dried by relatively short baking times thereby reducing the overall energy requirements of drying and the potential degradation of omega-3 HUFAs due to long time periods at high temper-atures. In addition, heat from the extrusion process can degrade some of the unwanted toxic compounds commonly found in the additional component which can, for example, inhibit egg laying by hens or cause animals to go off of their feed.

The present invention will be described in more detail by way of working examples. Species meeting the selection criteria described above have not been described in the prior art. By employing these selection criteria, over 25 potentially promising strains have been isolated from approximately 1000 samples screened. Out of the approximate 20,500 strains in the American Type culture Collection (ATCC) , 10 strains were later identified as belonging to the same taxonomic group as the strains isolated. Those strains still viable in the Collection were procured and used to compare with strains isolated and cultured by the disclosed procedures. The results of this comparison are presented in Examples 4 and 5 below.

The most recent taxonomic theorists place Thraustochydrids with the algae or algae-like protists. All of the strains of unicellular microorganisms disclosed and claimed herein are members of the order Thraustochytriales (Order: Thraustochytriales; Family: Thraustochytriaceae;
Genus: Thraustochytr.ium or Sch4zochytrium). For general purposes of discussion herein, these microorganisms will be called microflora to better denote their uncertain exact taxonomic position.

The strains identified below were deposited under the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purpose of Patent Procedure. All restrictions on the availability to the public of the materials so deposited will be irrevocably removed upon the granting of a patent. Vach deposit will be stored for a period of at least five years after the most recent request for the furnishing of a sample of the deposited microorganism is received by the American Type culture Collection (ATCC) , and, in any case, for a period of at least years after the date of the deposit.

EXAMPLES
Example 1. Collection and Screening A 150ml water sample was collected from a shallow, inland saline pond and stored in a sterile polyethylene bottle. Special effort was made to include some of the living plant material and naturally occurring detritus (decaying plant and animal matter) along with the water sample. The sample was placed on ice until return to the laboratory. In the lab, the water sample was shaken for 15-30 seconds, and 1-10ml of the sample was pipetted or poured into a filter unit containing 2 types of filters: 1) on top, a sterile 47mm diameter Whatman #4 filter having a pore size about 25 m; and 2) underneath the Whatman filter, a 47mm diameter polycarbonate filter with about 1.0 m pore size.
Given slight variations of nominal pore sizes for the filters, the cells collected on the polycarbonate filter range in size from about 1.0 m to about 25 m.

The Whatman filter was removed and discarded. The polycarbonate filter was placed on solid F-1 media in a petri plate, said media consisting of (per liter): 600m1 seawater (artificial seawater can be used), 400ml distilled water, 10g agar, 1g glucose, ig protein hydrolysate, 0.2g yeast extract, 2m1 0.1 M KH2PO4, iml of a vitamin solution (A-vits) (Containing 100mg/l thiamine, 0.5mg/i biotin, and 0.5mg/i cyanocobalamin), 5ml of a trace metal mixture (PII metals, containing per liter: 6.Og Na2EDTA, 0.29g FeC136H2O, 6.84g H3BO3, 0.86 MnC124H2O, 0.06g ZnC12, 0.026g COC126H2O, (0.052g NiSO4X2O, 0.002g CuSo45H2o, and 0.0058 NaMoo42HZO, and 500mg each of streptomycin sulfate and penicillin-G. The agar plate was incubated in the dark at 301C. After 2-4 days numerous colonies appeared on the filter. colonies of unicellular microflora (except yeast) were picked from the plate and restreaked on a new plate of similar media composition-Special attention was made to pick all colonies consisting of colorless white cells. The new plate was incubated at 30"C and single colonies picked after a 2-4 day incubation period. Single colonies were then picked and placed in 50m1 of liquid medium containing the same organic enrichments as in the agar plates. These cultures were incubated for 2-4 days at 30"C on a rotary shaker table (100-200 rpm). When the cultures appeared to reach maximal density, 20-40zul of the culture was harvested, centrifuged and lyophilized. The sample was then analyzed by standard, well-known gas chromatographic techniques 0C.9-, Lepage anc Roy, "Improvement gecovery of Fatty Acid Through Direct Transesterlf1.Cat10n without Fra.or Extraction or purification", pp. 1391 - 1396, 1984, J. Lipid Res., vol. 25 to identify the fatty acid content of the strain- Those strains with omega-3 HUFAs were thereby identified, and cultures of these strains were maintained for further screening.

Using the collection and screening process outlined above, over 150 strains of unicellular microflora have been isolated which have high omega-3 HuFA contents as a percent of total fatty acids and which exhibit growth over a temperature range from 15-48"C. Strains can also be isolated which have less than It (as % of total fatty acids) of the undesirable C20;4n-6 and C22:5n-6 HtFAs for some applications. Strains with high omega-6 content can also -21 be. isolated. Strains of these microflora can be repeatedly isolated from the same location using the procedure outlined above. A few of the newly isolated strains have very similar fatty acid profiles. The possibility that some are duplicate isolates of the same strain cannot be ruled out at present.
Further screening for other desirable traits such as salinity tolerance or ability to use at variety of carbon and nitrogen sources can than be carried out using a similar process.

The pH of the solution was adjusted to 7.0 and the solution was filter sterilized. Sterile solutions of corn steep liquor (4g/40m1; pH 7.0) and yeast extract (lg/40ml; pH 7.0) were prepared. To one set of M-5 medium flasks, the following amount of yeast extract solution was added: 1) 2m1;
2) 1.5m1; 3) iml; 4) 0.5m1; and 5) 0.25m1. To another set of M-5 medium flasks the yeast extract and corn steep liquor solutions were added at the following levels: 1) 2ml yeast extract; 2) 1.5m1 yeast extract and 0.5m1 corn steep liquor;
3) 1.0ml yeast extract and 1.0ml corn steep liquor; 4) 0.5m1 yeast extract and 1.5ml corn steep liquor; and 5) 2m1 corn steep liquor. One ml of the culture in F-1 medium was used to inoculate each flask. They were placed on a rotary shaker at 27 C for 48 hr. The cells were harvested by centrifugation and the yield of cells (as ash-free dry weight) was determined. The results are shown in Table 1. The results indicate the addition of yeast extract up to 0.8g/l of medium can increase the yield of cells. However, addition of corn steep liquor is even more effective and results in twice the yield of treatments with added yeast extract. This is very advantageous for the economic production of cells as corn steep liquor is much less expensive than yeast extract.

Enhanced HUFA Content of Strains Isolated by Method in Example 1 Compared to ATCC Strains (Previously Known Strains) A battery of 151 newly isolated strains, selected according to the method described in Example 1, were sampled in late exponential phase growth and quantitatively analyzed for HUFA content by gas-liquid chromatography. All strains were grown either in Ml medium or liquid FFM medium, which-ever gave highest yield of cells. M1 medium has the same composition as M5 medium, except that the concentrations of glucose and glutamate are 1 g/l. Additionally, five previously isolated Thraustochytrium or Schizochytrium species were obtained from the American Type Culture Collection, representing all the strains which could be obtained in viable form from the collection. These strains were: T. aureum (ATCC No. 28211), T. aureum (ATCC No. 34304), T. roseum (ATCC No. 28210), T. straitum (ATCC No. 34473) and S. aggregatum (ATCC No. 28209). The strains all exhibited abbreviated growth in conventional media, and generally showed improved growth in media of the present invention, including M5 medium and FFM medium. The fatty acid production of each of the known strains was measured as described, based upon the improved growth of the strains in media of the invention.

Fatty acid peaks were identified by the use of pure compounds of known structure. Quantitation, in terms of percent by weight of total fatty acids, was carried out by integrating the chromatographic peaks. Compounds identified were: palmitic acid (C16:0), C20:4n-6 and C22:1 (which were WO 94/08467 21 4 6 x 35 PCF/US93/09679 not resolved separately by the system employed), C20:5n-3, C22:5n-6, C22:5n-3, and C22:6n-3. The remainder, usually lower molecular weight fatty acids, were included in the combined category of "other fatty acids." Total omega-3 fatty acids were calculated as the sum of 20:5n-3, 22:5n-3 and 22:6n-3. Total omega-6 fatty acids were calculated as the sum of the 20:4/22:1 peak and the 22:5n-6 peak.

The results are shown in Tables 2-3 and illustrated in Figs. 1-3. From Table 2 it can be seen that large numbers of strains can be isolated by the method of the invention, and that large numbers of strains outperform the previously known strains by several important criteria. For example, 102 strains produced at least 7.8% by weight of total fatty acids C20:5w3, a higher percentage of that fatty acid than any previously known strain. Strains 23B (ATCC No. 20892) and 12B (ATCC No. 20890) are examples of such strains.
Thirty (30) strains of the invention produced at least 68%
by weight of total fatty acids as omega-3 fatty acids, more than any previously known strain. Strain 23B (ATCC No.

20892) is an example of such strains. Seventy-six (76) strains of the invention yielded not more than 10% by weight of total fatty acids as omega-6 fatty acids, considered undesirable components of the human diet, lower than any previously known strain. Strains 23B (ATCC No. 20892) and 12B (ATCC No. 20890) are examples of such strains. In addition, there are 35 strains of the invention that produce more than 25% by weight of total fatty acids as omega-6 fatty acids, more than any previously known strain. While such strains may have a more narrow range of uses for dietary purposes, they are useful as feedstock for chemical synthesis of eicosanoids starting from omega-6 fatty acids.

In addition, the data reveal many strains of the invention which produce a high proportion of total omega-3 fatty acids as C22:6n-3. In Table 3, 48 of the strains shown in Table 2 were compared to the previously known strains, showing each of C20:5n-3, C22:5n-3 and C22:6n-3 as percent by weight of total omega-3 content. Fifteen strains had at least 94% by weight of total omega-3 fatty acids as C22 : 6n-3 , more than any previously known strain. Strain S8 (ATCC No.
20889) was an example of such strains. Eighteen strains had at least 28% by weight of total omega-3 fatty acids as C20:5n-3, more than any previously known strain. Strain 12B
(ATCC No. 20890) was an example of such strains.

All of the previously known strains had less than 67% omega-3 fatty acids (as % of total fatty acids) and greater than 10.6%
omega-6 (as % of total fatty acids).

Example 5. Enhanced Growth Rates of Strains Isolated by Method in Example 1 Compared to ATCC Strains (Previously Known Strains) Cells of Schizochytrium sp. S31 (ATCC No. 20888), Schizochytrium sp. S8 (ATCC No. 20889), Thraustochytrium sp.
S42, Thraustochytrium sp. U42-2, Thraustochytrium sp. S42 and U30, (all isolated by the method of Example 1) and Thraustochytrium aureum (ATCC #28211) and Schizochytrium aggregatum (ATCC #28209) (previously known strains) were picked from solid F-1 medium and placed into 50m1 of M-5 medium. The pH of the solution was adjusted to 7.0 and the solution was filter sterilized. After three days of growth on an orbital shaker (200 rpm, 27 C), 1-2m1 of each culture was transferred to another flask of M-5 medium and placed on the shaker for 2 days. The cultures (1-2m1) were then transferred to another flask of M-5 medium and placed on the shaker for 1 day. This process ensured that all cultures were in the exponential phase of growth. These later cultures were then used to inoculate two 250m1 flasks of M-5 medium for each strain. These flasks were than placed on shakers at 25 C and 30 C, and changes in their optical density were monitored on a Beckman DB-G spectrophotometer (660nm, 1cm path length). Optical density readings were taken at the following times: 0, 6, 10, 14, 17.25, 20.25 and 22.75 hours.
Exponential growth rates (doublings/day) were then calculated from the optical density data by the method of Sorokin (1973). The results are presented in Table 4 and illustrated (normalized to the growth of strain U30 at 25 C) in Fig. 4.

The data indicate that the strains isolated by the method in Example 1 have much higher growth rates than the previously known ATCC strains at both 25 C and 30 C, even under the optimized phosphate levels essential for continuous growth. Strains of Thraustochytriales isolated from cold Antarctic waters have not been shown to grow at 30 C.

Enhanced Production Characteristics (Growth and Lipid Induction) of Strains Isolated by Method in Example 1 Compared to ATCC Strains (Prior Art Strains) Cells of Schizochytrium sp. S31 (ATCC No. 20888), Schizochytrium sp. S8 (ATCC No. 20889) (both isolated by the method of Example 1) and Thraustochytrium aureum (ATCC
#28211) and Schizochytrium aggregatum (ATCC #28209) (prior art strains) were picked from solid F-1 medium and placed into 50m1 of M-5 medium (see Example 3). The pH of the solution was adjusted to 7.0 and the solution was filter sterilized. After three days of growth on an orbital shaker (200 rpm, 27 C), 1-2ml of each culture was transferred to another flask of M-5 medium and placed on the shaker for 2 days. The ash-free dry weights for each of these cultures were then quickly determined and then 3 , 29mg of each culture was pipetted into two 250m1 erlenmeyer flasks containing 50m1 of M-5 medium. These flasks were placed on a rotary shaker (200 rpm, 27 C). After 24 hours 20m1 portions of each culture were then centrifuged, the supernatants discarded, and the cells transferred to ?50ml erlenmayer flasks containing 50 ml of M-5 medium without any glutamate (N-source). The flasks were placed back on the shaker, and after another 12 hours they were sampled to determine ash-free dry weights and quapt3,.fy fatty acid contents by the method of Lepage and Roy, "Improved Recovery of Fatty Acid Through Direct Transescerification without Prior Lxtr4ction or Purification", pp.1391-1396,1954, J. Lipid Res., Vol. 25. The results are illustrated (normalized to the yields of ATCC No. 28211, previously known strain) in Fig. 5. The results indicate that the strains isolated by the method of Example 1 produced 2-3 times as much ash-free dry weight in the same period of time, under a combination of exponential growth and nitrogen limitation (for lipid induction) as the prior art ATCC strains. In addition, higher yields of total fatty acids and omega-3 fatty acids were obtained from strains of the present invention with strains S31 (ATCC No. 20888) producing 3-4 times as much omega-3 fatty acids as the prior art ATCC
strains.

Exa ple 7. gthance d Lower salinity Tolerance and Fatty Acid F o~ duction by Strains Isolated by Method in ramp e i Strains of 4 species of Thraustochytrids, Schi.zochytrium sp. S31 (ATCC No. 20888) and Thraustochytrium sp. U42-2 (ATCC
No. 20891) (both isolated and screened by the method of WO 94/08467 w 1 Example 1), and S. aggregatum (ATCC 28209) and T. aureum (ATCC 28210) (obtained from the American Type Culture Collection) were picked from solid F-i medium and incubated for 3-4 days at 27 C on a rotary shaker (200 rpm). A range of differing salinity medium was prepared by making the following dilutions of M medium salts (NaCl, 25g/1;
MgS04.7H20, 5g/l; KC1, 1g/l; CaCl 2, 200mg/l: 1) 100% (w/v M
medium salts; 2) 80% (v/v) M medium, 20% (v/v) distilled water; 3) 60% (v/v) M medium, 40% (v/v) distilled water; 4) 40% (v/v) M medium, 60% (v/v) distilled water; 5) 20% (v/v) M medium, 80% distilled water; 6) 15% (v/v) M medium, 85%
(v/v) distilled water; 7) 10% (v/v) M medium, 90% (v/v) distilled water; 8) 7% (v/v) M medium, 93% (v/v) distilled water; 9) 3% (v/v) M medium, 97% (v/v) distilled water; 10) 1.5% (v/v) M medium, 98.5% (v/v) distilled water. The following nutrients were added to the treatments (per liter) :
glucose, 5g; glutamate, 5g; yeast ext. , lg; (NH4) 2SO4, 200 mg; NaHCO3, 200 mg; PII metals, 5ml; A-vitamins solution, iml; and antibiotics solution, 2ml. Fifty ml of each of these treatments were inoculated with lml of the cells growing in the F-i medium. These cultures were placed on an orbital shaker (200 rpm) and maintained at 27 C for 48 hr. The cells were harvested by centrifugation and total fatty acids determined by gas chromatography. The results are illustrated in Fig. 6. Thraustochytrium sp. U42-2 (ATCC
No. 20891) isolated by the method of Example 1 can yield almost twice the amount of fatty acids produced by T. aureum (ATCC 28211) and over 8 times the amount of fatty acids produced by S. aggregatum (ATCC 28209). Additionally, U42-2 appears to have a wider salinity tolerance at the upper end of the salinity range evaluated. Schizochytrium sp. S31 (ATCC No. 20888), also isolated by the method in Example 1, exhibited both a high fatty acid yield (2.5 to 10 times that of the previously known ATCC strains) and a much wider range of salinity tolerance than the ATCC strains. Additionally, Schizochytrium sp. S31 (ATCC No. 20888) grows best at very low salinities. This property provides a strong economic advantage when considering commercial production, both because of the corrosive effects of saline waters on metal reactors, and because of problems associated with the disposal of saline waters.

Example 8. Cultivation/Low Salinity Fifty ml of M/10-5 culture media in a 250m1 erlenmeyer flask was inoculated with a colony of Schizochytrium sp. S31 (ATCC No. 20888) picked from an agar slant. The M/10-5 media contains: 1000ml deionized water, 2. 5g NaCl, 0. 5g MgSO4. 7H2O, 0.1g KC1, 0.02g CaC121 1.Og KH2PO4, 1.0g yeast extract, 5.Og glucose, 5.Og glutamic acids, 0.2g NaHCO3, 5ml PII trace metals, 2m1 vitamin mix, and 2m1 antibiotic mix. The culture was incubated at 30 C on a rotary shaker (200 rpm). After 2 days the culture was at a moderate density and actively growing. 20m1 of this actively growing culture was used to inoculate a 2 liter fermenter containing 1700m1 of the same culture media except the concentration of the glucose and glutamate had been increased to 40g/1 (M/10-40 media). The WO 94/08467 2142,35 PCT/US93/09679 fermenter was maintained at 30 C, with aeration at 1 vol/vol/min, and mixing at 300 rpm. After 48 hr, the concentration of cells in the fermenter was 21.7g/l. The cells were harvested by centrifugation, lyophilized, and stored under N2.

The total fatty acid content and omega-3 fatty acid content was determined by gas chromatography. The total fatty acid content of the final product was 39.0% ash-free dry weight. The omega-3 HUFA content (C20:5n-3, C22:5n-3 and C22 : 6n-3) of the microbial product was 25.6% of the total fatty acid content. The ash content of the sample was 7.0%.
Example 9. Diversity of Fatty Acid Content Growth and gas chromatographic analysis of fatty acid production by various strains as described in Example 4 revealed differences in fatty acid diversity. Strains of the present invention synthesized fewer different fatty acids than previously available strains. Lower diversity of fatty acids is advantageous in fatty acid purification since there are fewer impurities to be separated. For food supplement purposes, fewer different fatty acids is advantageous because the likelihood of ingesting unwanted fatty acids is reduced.
Table 5 shows the number of different HUFAs present, at concentrations greater than 1% by weight of total fatty acids for previously known strains, designated by ATCC number and various strains of the present invention.

Recovery Fifty ml of M5 culture media in a 250 ml erlenmeyer flask was inoculated with a colony of Schizochytrium sp. S31 (ATCC No. 20888) picked from an agar slant. The culture was incubated at 30 C on a rotary shaker (200 rpm) . After 2 days the culture was at a moderate density and actively growing.
20m1 of this actively growing culture was used to inoculate a 1 liter fermenter containing 1000ml of the same culture media except the concentration of the glucose and glutamate had been increased to 40g/l (M20 media). The fermenter was maintained at 30 C and pH 7.4, with aeration at 1 vol/min, and mixing at 400 rpm. After 48 hr, the concentration of the cells in the fermenter was 18.5g/l. Aeration and mixing in the fermenter was turned off. Within 2-4 minutes, the cells flocculated and settled in the bottom 250 ml of the fermenter. This concentrated zone of cells had a cell concentration of 72g/l. This zone of cells can be siphoned from the fermenter, and: (1) transferred to another reactor for a period of nitrogen limitation (e.g., combining the highly concentrated production of several fermenters); or (2) harvested directly by centrifugation or filtration. By preconcentrating the cells in this manner, 60-80% less water has to be processed to recover the cells.

Example 11. Utilization of a Variety of Carbon and Nitrogen Sources Fifty ml of M5 culture media in a 250m1 erlenmeyer flask was inoculated with a colony of Schizochytrium sp. S31 (ATCC
No. 20888) or Thraustochytrium sp. U42-2 (ATCC No. 20891) picked from an agar slant. The M5 media was described in Example 3 except for the addition of 2ml vitamin mix, and 2m1 antibiotic mix. The culture was incubated at 30 C on a rotary shaker (200 rpm). After 2 days the culture was at a moderate density and actively growing. This culture was used to inoculate flasks of M5 media with one of the following substituted for the glucose (at 5g/1): dextrin, sorbitol, fructose, lactose, maltose, sucrose, corn starch, wheat starch, potato starch, ground corn; or one of the following substituted for the glutamate (at 5g/1) : gelysate, peptone, tryptone, casein, corn steep liquor, urea, nitrate, ammonium, whey, or corn gluten meal. The cultures were incubated for 48 hours on a rotary shaker (200 rpm, 27 C).

20890) was produced in shake flasks in M-5 medium (see Example 3) at 25 C. Cellular biomass of Thraustochytrium sp. S31 (ATCC 20888) was produced in shake flasks in M/10-5 medium (see Example 8) at 27 C. The cells of each strain were harvested by centrifugation. The pellet was washed once with distilled water and recentrifuged to produce a 50%
solids paste. The resulting paste was resuspended in sea water and then added to an adult brine shrimp culture as a feed supplement. The brine shrimp had previously been reared on agricultural waste products and as a result their omega-3 HUFA content was very low, only 1.3 - 2.3% of total fatty acids (wild-caught brine shrimp have an average omega-3 HUFA
content of 6 - 8% total fatty acids) . The brine shrimp (2 -3/mL) were held in a 1 liter beaker filled with sea water and an airstone was utilized to aerate and mix the culture.
After addition of the feed supplement, samples of the brine shrimp were periodically harvested, washed, and their fatty acid content determined by gas chromatography. The results are illustrated in Figs. 7 and S. When fed the thraustochytrid-based feed supplement as a finishing feed, the omega-3 content of the brine shrimp can be raised to that of wild-type brine shrimp within 5 hours if fed strain 12B
or within 11 hours when fed strain S31. The omega-3 HUFA
content of the brine shrimp can be greatly enhanced over that of the wild type if fed these feed supplements for up to 24 hours. Additionally, these feed supplements greatly increase the DHA content of the brine shrimp, which is generally only reported in trace levels in wild-caught brine shrimp.
Example 13. Use of Sodium Sulfate in Culture Medium This example illustrates that omega-3 production and total fatty acid content is not harmed and can be the same or better when using sodium sulfate instead of sodium chloride as the sodium salt in a fermentation medium.
