Abstract

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

Claims

1. A microbial oil comprising a triglyceride fraction of from 75% to 95% by weight, wherein the docosahexaenoic acid content of the triglyceride fraction is from 40% to 80% by weight, wherein the arachidonic acid content of the triglyceride fraction is from 0.1% by weight to 1.5% by weight, wherein said microbial oil further comprising an effective amount of at least one added antioxidant to provide oxidative stability.

2. The microbial oil of claim 1, wherein the arachidonic acid content of the triglyceride fraction is from 0.1% by weight to 0.5% by weight.

3. The microbial oil of claim 1, wherein the arachidonic acid content of the triglyceride fraction is from 0.1% by weight to 0.25% by weight.

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

5. The food product of claim 4, wherein the food product is an infant formula.

6. The food product of claim 5, wherein the infant formula can be consumed by premature infants.

7. The food product of claim 4, wherein the food product is milk, a beverage, a therapeutic drink, a nutritional drink, or a combination thereof.

8. The food product of claim 4, wherein the food product is an additive for animal or human food.

9. The food product of claim 4, wherein the food product is a nutritional supplement.

10. The food product of claim 4, wherein the food product is an animal feed.

11. The animal feed of claim 10, wherein the animal feed is an aquaculture feed.

12. The animal feed of claim 10, wherein the animal feed is a domestic animal feed, a zoological animal feed, a work animal feed, a livestock feed, or a combination thereof.
