The purpose of the present invention is to provide an oil/lipid that contains dihomo-γ-linolenic acid at a higher purity. Provided is a microbial oil/lipid that is specified by a high content of dihomo-γ-linolenic acid contained therein and/or a reduced content of undesirable constituting fatty acid(s).

Dihomo-gamma-linolenic acid-containing microbial oil/lipid with reduced arachidonic acid content

Docosahexaenoic acid-containing oil containing docosahexaenoic acid in a concentration of 40 wt. % or more of the total weight of fatty acids in the oil, and having an endothermic peak temperature determined by differential scanning calorimetry (DSC) of 15° C. or lower; a biomass including the same; and a method for producing docosahexaenoic acid-containing oil including obtaining a biomass by culturing microorganisms of the genuscapable of producing this docosahexaenoic acid-containing oil, recovering the biomass after culture, and extracting the oil from the biomass after recovery.

Docosahexaenoic acid-containing oil containing docosahexaenoic acid in a concentration of 40 wt. % or more of the total weight of fatty acids in the oil, and having an endothermic peak temperature determined by differential scanning calorimetry (DSC) of 15&#xb0; C. or lower; a biomass including the same; and a method for producing docosahexaenoic acid-containing oil including obtaining a biomass by culturing microorganisms of the genuscapable of producing this docosahexaenoic acid-containing oil, recovering the biomass after culture, and extracting the oil from the biomass after recovery.

Provided is a dried powder of microorganisms, which is highly suitable for processing and has excellent usefulness as one component of various products. The present invention provides: a dried powder of microorganisms, the dried powder exhibiting a brightness of 55 or more and a chromaticness of 18 or less; and a method for producing a dried powder of microorganisms, the method comprising: washing microorganisms at least once with a liquid having an osmotic pressure lower than that of a liquid culture medium for culturing the microorganisms; and drying and heating the microorganisms after the washing to thereby obtain the dried powder of the microorganisms, which exhibits a brightness of 55 or more and a chromaticness of 18 or less.
