The invention relates to a microbial biomass composition produced from a heterotrophic fermentation whose fatty acid profile exhibits an eicosapentaenoic acid (EPA) to arachidonic acid (ARA) ratio of about 11:1 or more, an EPA to total co-concentrating fatty acid ratio of about 8:1 or more, extract compositions, and methods of producing such compositions.

Compositions comprising eicosapentaenoic acid suitable for high purification

Eicosapentaenoic acid (EPA) compositions and EPA-rich polar lipids for prophylactic or therapeutic applications are described. Production from certain cultured micro-organisms (like) promotes synthesis of EPA, including polar lipids including EPA. The EPA-rich polar lipids themselves may be used as polar compounds. EPA can be selectively hydrolysed from particular positions in isolated polar lipids by lipase activity, then optionally further purified. The process bypasses reliance on diminishing fish stocks and on physico-chemical processes that may not adequately separate desirable n-3 HUFAs from unwanted products like DHA also found in fish oil and cultured organisms.

Production of ultrapure EPA and polar lipids from largely heterotrophic culture

The invention relates to a microbial biomass composition produced from a heterotrophic fermentation whose fatty acid profile exhibits: an eicosapentaenoic acid (EPA) to arachidonic acid (ARA) ratio of about 11:1 or more; an EPA to total co-concentrating fatty acid ratio of about 8:1 or more, extract compositions, and methods of producing such compositions.
