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.
1. A microbial oil comprising a triglyceride fraction of at least 70% by weight, wherein the docosahexaenoic acid content of the triglyceride fraction is at least 45% by weight, and wherein the oil comprises 1.5% by weight or less of arachidonic acid.
2. The microbial oil of claim 1 , wherein said docosahexaenoic acid content of the triglyceride fraction is at least 60% by weight.
3. The microbial oil of claim 1 , wherein said docosahexaenoic acid content of the triglyceride fraction is at least 80% by weight.
4. The microbial oil of claim 1 , wherein said docosahexaenoic acid content of the triglyceride fraction is at least 90% by weight.
5. The microbial oil of claim 1 , further comprising an arachidonic acid content of the triglyceride fraction of between 0.1% and 1.5% by weight.
6. The microbial oil of any one of claims 1 to 5 , wherein said microbial oil further comprising an effective amount of at least one added antioxidant to provide oxidative stability.
7. A food product composition for animals or humans, comprising the microbial oil of any one of claims 1 to 6 .
8. The food product of claim 7 , wherein the food product is an infant formula.
9. The food product of claim 7 , wherein the food product is milk, a beverage, a therapeutic drink, a nutritional drink, or a combination thereof.
10. The food product of claim 7 , wherein the food product is an additive for animal or human food.
11. The food product of claim 7 , wherein the food product is a nutritional supplement.
12. The food product of claim 7 , wherein the food product is an animal feed.
13. The animal feed of claim 12 , wherein the animal feed is an aquaculture feed.
14. The animal feed of claim 12 , wherein the animal feed is a domestic animal feed, a zoological animal feed, a work animal feed, a livestock feed, or a combination thereof.
