The effect of ethanol (final concentration is 0.3 and 0.5%) on biomass yield and composition (content of nucleic acids, proteins, lipids, and chlorophyll a and b, ?-carotene, and exopolysaccharides) and morphology of the cells Dunaliella viridis in a quasi-mode of cultivation was investigated. It has been found that addition of ethanol in the culture medium to a final concentration of 0.3% increased output 2-fold compared with the quasi-continuous cultivation without alcohol and 2.5 times compared with a cumulative cultivation. Increasing the concentration of ethanol in the medium to 0.5% reduced the biomass yield of Dunaliella viridis compared with 0.3% alcohol concentration. Ethanol increased the output exopolysaccharides into culture medium and changed morphology and Dunaliella viridis motility.

Key words: D. viridis biomass, quasi-continuous cultivation, effect of ethanol.
