Abstract

The present invention is directed to isolated microorganisms as well as strains and mutants thereof, biomasses, microbial oils, compositions, and cultures; methods of producing the microbial oils, biomasses, and mutants; and methods of using the isolated microorganisms, biomasses, and microbial oils.

First claim

What is claimed:

1. A microbial oil comprising a triacylglycerol fraction which is between 75% to 98% by weight of said microbial oil, wherein between 10% to 30% by weight of the fatty acids in the triacylglycerol fraction is eicosapentaenoic acid, wherein between 30% to 50% by weight of the fatty acids in the triacylglycerol fraction is docosahexaenoic acid, and wherein less than 5% by weight of the fatty acids in the triacylglycerol fraction is arachidonic acid, wherein said microbial oil is produced by an isolated strain of thraustochytrid, wherein said microbial oil also comprising an effective amount of at least one added antioxidant to provide oxidative stability.

2. The microbial oil of claim 1 , wherein said triacylglycerol fraction is triacylglycerol fraction of between 80% to 98% by weight.

3. The microbial oil of claim 2 , wherein said triacylglycerol fraction is of between 90% to 98% by weight.

4. The microbial oil of claim 1 , wherein between 10% to 25% by weight of the fatty acids in the triacylglycerol fraction is eicosapentaenoic acid.

5. The microbial oil of claim 4 , wherein between 5% to 25% by weight of the fatty acids in the triacylglycerol fraction is eicosapentaenoic acid.

6. The microbial oil of claim 3 , wherein between 10% to 20% by weight of the fatty acids in the triacylglycerol fraction is eicosapentaenoic acid.

7. The microbial oil of claim 1 , wherein between 35% to 50% by weight of the fatty acids in the triacylglycerol fraction is docosahexaenoic acid.

8. The microbial oil of claim 3 , wherein between 30% to 40% by weight of the fatty acids in the triacylglycerol fraction is docosahexaenoic acid.

9. The microbial oil of claim 1 , wherein 3% or less by weight of the fatty acids in the triacylglycerol fraction is arachidonic acid.

10. The microbial oil claim 8 , wherein 2% or less by weight of the fatty acids in the triacylglycerol fraction is arachidonic acid.

11. A food product, cosmetic, or pharmaceutical composition for humans, comprising the microbial oil of claim 1 .

12. The food product of claim 11 , wherein the food product is an infant formula.

13. The food product of claim 12 , wherein the infant formula can be consumed by premature infants.

14. The food product of claim 11 , wherein the food product is milk, a beverage, a therapeutic drink, a nutritional drink, or a combination thereof.

15. The food product of claim 11 , wherein the food product is a nutritional supplement.

16. An animal feed comprising the microbial oil of claim 1 .

17. The animal feed of claim 16 , wherein the animal feed is an aquaculture feed.

18. The animal feed of claim 16 , wherein the animal feed is a domestic animal feed, a zoological animal feed, a work animal feed, a livestock feed, or a combination thereof.

19. A biomass comprising the microbial oil of claim 1 .

20. An animal feed supplement comprising the microbial oil of claim 1 .
