Abstract:
The effect of 5 store methods at 3 different temperature on ice nucleation activity of INA bacteria were evaluated. The results showed that some store methods could decrease the ice nucleation activity. The effect increased as the temperature of increased. The effect on survival and on activity is different. Different strains had different susceptibility and adaptability. It was found that the freeze-drying method storing at -20℃ and freezing in sterile distilled water storing at -20℃ could be used for most INA bacteria. Freezing in 10% glycerin could not be used for the store of INA bacteria.
