The effect of temperature in hydrostatic pressure treatment on the germination of B. stearothermophilus spores was investigated. There were optimum temperatures in the germination ratio in the treatment at 10, 20, 30 and 40MPa for 720min. There was also an optimum temperature on the germination of B. stearothermophilus spores by chemical germinants at 0.1MPa (under atmospheric pressure). Therefore, it was considered that the cause of optimum temperature of inactivation was the optimum temperature of germination enzymes under hydrostatic pressure below 40MPa.
