[Study of induction of mitochondrial mutations in Saccharomyces cerevisiae yeasts following exposure to ethyl alcohol].
The kinetics of the killing and petite-inducing effects of ethanol has been studied at 6-30% concentrations. The results obtained indicate that the ploidy of cells or holding them under no-growth conditions do not influence on their survival. Ethanol increased the number of respiration-deficient cells from spontaneous level (0.46%) up to nearly half of all survivors at 24% and 30% ethanol concentrations. The genetic analysis has shown the mitochondrial nature of induced respiration deficiency.
