The viability of Saccharomyces cerevisiae suspended in NaCl solution decreased markedly when the suspension was frozen to the temperature of formation of the eutectic mixture, whereas in suspension in CaCl_2 the cells survived well. The difference between two groups of compounds, characterized respectively by NaCl and CaCl_2 in freeze-thaw damage was studied.The viability of yeast cells decreased markedly when the formation of the eutectic mixture was completed between about -10 and -40℃, but decreased little when the formation of the eutectic mixture was not completed in this range. These results suggest that compounds with a eutectic temperature in this range will give lower survival of yeast cells in the freezing process.
