It was studied the effect of lipid components of corn vinasse on the growth intensity of yeast Rhodosporidium diobovatum IMB Y – 5023. It was established that when cultured on the primary corn vinasse the yeast growth intensity was quite low, and in such form it cannot be used for industrial production of yeast biomass. For use of corn vinasse in industrial production of yeast biomass it must be preliminary prepared, using flotation or separation for dividing into fractions and, respectively, for removing of mechanical particles and some lipids, inhibiting the growth of Rhodosporidium diobovatum IMB Y – 5023, рН of corn vinasse must be 5.0 – 6.0.After such vinasse modification, the yield of Rh. diobovatum IMB Y-5023 dry biomass was increased by 44% compared to primary medium, and at the same time Rh. diobovatum IMB Y – 5023 actively assimilated the residual lipid components of corn vinasse, which provided quite intensive growth of Rh. diobovatum IMB Y – 5023 culture.For optimal growth and high yield of Rhodosporidium diobovatum IMB Y – 5023 biomass on corn vinasse the amount of its lipids must be about 300 mg/ml, and at the concentration of 400 mg/ml their growth is inhibited. Also, it was found that when the media contained lipids with concentrations from 50 to 400 mg/ml and without mechanical particles, yeast cells formed aggregates.

Keywords: Yeast, lipids, cornvinasse, Rhodosporidium diobovatum IMBY – 5023, growth intensity,biomass.
