Summary

Low-temperature adaptation and cryoprotection were studied in the thermophilic lactic acid bacterium Streptococcus thermophilus CNRZ302. S. thermophilus actively adapts to freezing during a pretreatment at 20 °C, resulting in an approximately 1000-fold increased survival after four freeze-thaw cycles compared to mid-exponential-phase cells grown at an optimal temperature of 42 °C. No adaptation is observed when cells are exposed to a temperature (10 °C) below the minimal growth temperature of the strain (just below 15 °C).
