FIELD: biotechnology.
SUBSTANCE: proposed are a method for producing PUFA-containing biomass by culturing PUFA-producing cells of the Thraustochytriaceae family in a fermentation medium in conditions of sulphate content adjustment so that sulphate is always present in the medium for the entire period of the oil production phase at a concentration of 0.01 to 2 g per kg of lipid-free biomass for at least a second half of the oil production phase; and PUFA-containing biomass produced by the claimed method.
EFFECT: inventions increase the output of the target product characterised by a high mass fraction of polyunsaturated fatty acids (PUFA).
