[Cryostability of yeast cells and their sensitivity to basic factors of freezing].
The cryostability of Saccharomyces cerevisiae cells was found to correlate with their sensitivity to some physico-chemical factors of freezing. The threshold of their resistance to the main factors of cryoconservation (a low-temperature shock, the presence of a salt, a change in the pH of the medium) was determined at a temperature value physiological for this microorganism. This work was done in order to substantiate and predict optimal freezing regimes while making microbial cells pass into the state of deep cryptobiosis.
