The effects of slow chilling (2°C min−1) and rapid chilling (2,000°C min−1) were investigated on the survival and membrane fluidity of Escherichia coli, of Bacillus subtilis, and of Saccharomyces cerevisiae. Cell death was found to be dependent on the physiological state of cell cultures and on the rate of temperature downshift. Slow temperature decrease allowed cell stabilization, whereas the rapid chilling induced an immediate loss of viability of up to more than 90 and 70% for the… CONTINUE READING
