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

The invention relates to methods of producing a diatom biomass. More particularly, the invention relates to methods to produce a diatom biomass using a continuous culture to produce a volumetric production rate of biomass of at least 20 g dry weight/L/day, wherein the culture medium is designed to provide the essential nutrients to maintain the diatom in log phase growth. In a preferred cmbodimcnt the biomass comprises highly unsaturated fatty acid.
