Краткое описание

The introduction of ethanol into the culture medium for Chlorella vulgaris Beijer up to final concentrations of 0.1, 0.3, 0.5, and 0.7 % on the fourth day of growth was found on the ninth day to increase the cell biomass 4.3, 9.0, 7.5, and 5.4 times, respectively, as compared with the control. An S-shaped dose-dependence was observed. The 0.3, 0.5, and 0.7 % concentration of ethanol in the culture medium enhanced the content of protein in cells 1.6, 3.0, and 1.9 times. In this case protein excretion into the medium was twice as high irrespective of the alcohol concentration in the medium. The introduction of ethanol at concentrations of 0.1, 0.3, 0.5, and 0.7 % caused no onsistent changes in the content of triacylglycerides in the Ch. vulgaris cells and decreased the content of non-esterified fatty acids 1.4, 1.9, 1.7, and 1.9 times, respectively. The employment of radioactively labeled alcohol at 0.3 % concentration showed that carbon composing ethanol was incorporated into the composition of DNA and RNA, and to a lesser extent into the composition of the proteins and lipids of the Ch. vulgaris cells. This attests that alcohol has a trophic function in Ch. vulgaris cells. As to the blue-green algae (Spirulina platensis (Nordst.) Geitl.), ethanol is highly toxic and not subjected to cell metabolism.
