The influence of oxidizing, thermal and ethanol stresses on the survival rate of yeast Yarrowia lipolytica was investigated.
It is shown that many stressors reduce the growth and development of the yeast, however, the survival
rate can be raised by cell preprocessing with non-lethal doses of stressors. Such preprocessing leads to cross tolerance.
Stressors exert an inhibitory action on the yeast breath intensity, but the cell survival rate increases due to the
functioning of cyanide-resistant alternative oxidase whose level of activity increases in comparison with the main
respiratory chain.
