FIELD: chemistry.
SUBSTANCE: invention relates to method of obtaining 9-decen-2-one. Method includes cultivation of said mould, belonging to family Aspergillaceae or Mortierellaceae, addition of undecylenic acid as substrate in fermentation medium with consumption from 0.1 to 0.9 g/l/hour in presence of oil, substrate bioconversion in 9-decen-2-one, its extraction and purification. As oil, used is oil, selected from the group, containing traditional food oils or triglycerides, which contain short-chained fatty acids, or white oils.
EFFECT: invention makes it possible to obtain 9-decen-2-one with output 8-16,5 g/l and high degree of purification 99%.
