METHOD OF PRODUCING LIPIDS WITH HIGH EICOSAPENTAENOIC ACID CONTENT

摘要

A lipid-producing microorganism is provided which can efficiently produce EPA. This mutant microorganism is obtained by introducing a foreign Δ17 desaturase gene, and one or more of a foreign Δ5 desaturase gene and a foreign Δ12 desaturase gene into a microorganism capable of producing ω9 highly unsaturated fatty acids or a microorganism having high arachidonic acid content in a fatty acid composition, and, after 10 days of culturing at 20°C or greater, the eicosapentaenoic acid content in the fatty acid composition is 20% or greater.
