Study on supercooling release in encapsulated ice system -2nd report: evaluation of the supercooling release agent using the microorganism

摘要

As regards the supercooling phenomena which is important matter in encapsulated ice system, we studied the supercooling release agent using the microorganism. Though the nucleation active bacteria had the high super cooling release ability, it was proved that the performance gradually lowered in long terms continuous use, when the live microorganism was used. In order to solve this problem, the sterilization treatment of the microorganism was examined and it was clarified that there was the high effect in the ultraviolet irradiation. In addition, the persistence of the supercooling release ability is improved by freeze-drying treatment.
