Eicosapentaenoic acid-producing microorganisms, fatty acid compositions, and methods of making and uses thereof

摘要

Disclosed is a method of making a biomass of a microorganism having fatty acids and a concentration of EPA, comprising: (a) fermenting the microorganism in a fermenter vessel to produce a biomass wherein the microorganism comprises a Thraustochytrid that produces a biomass having at least 3% EPA of the total weight of the fatty acids; and (b) adjusting the amount of the biomass in the vessel to attain a desired EPA level in the biomass. Also disclosed is an oil extracted from the biomass and its use in a feed product.
