PRODUCTION METHOD OF LIPID WITH HIGH CONTENT OF EICOSAPENTAENOIC ACID

摘要

PROBLEM TO BE SOLVED: To provide lipid producing microorganisms that can produce EPA efficiently.SOLUTION: The present invention provides a mutation microorganism obtained by introducing, into a microorganism having a metabolic pathway of ω6 highly unsaturated fatty acids, a foreign Δ15 desaturase gene, or a foreign Δ12 desaturase gene and either one or more of the foreign Δ15 desaturase gene and foreign Δ17 desaturase gene, and the content of eicosapentaenoic acid in the fatty acid composition after the culture under the condition of 20°C or more for 10 days is 20% or more.SELECTED DRAWING: None
