Microbial oil containing fatty acids obtained from stramenopile and method of producing the same

A microbial oil comprising a fatty acid obtained from a microorganism in which the fatty acid is highly accumulated, the microbial oil comprising:

• (a) 1.5% or more of arachidonic acid (AA) based on a total amount of fatty acid;
• (b) 0.2% or more of dihomo-γ-linolenic acid (DGLA) based on the total amount of fatty acid;
• (c) 0.04% or more of eicosatetraenoic acid (ETA) based on the total amount of fatty acid;
• (d) 3.8% or more of eicosapentaenoic acid (EPA) based on the total amount of fatty acid;
• (e) 13.7% or less of n-6 docosapentaenoic acid (n-6DPA) based on the total amount of fatty acid;
• and
• (f) 43.9% or less of docosahexaenoic acid (DHA) based on the total amount of fatty acid,
• wherein the microorganism belongs to a class of Labyrinthulomycetes in which a gene associated with fatty acid biosynthesis has been disrupted or an expression of the gene has been inhibited.
