The heating is used for sterilization generally. On the other hand, there is a large demand for non-heating sterilization technology in the many fields. An underwater shock wave causes the high pressure that makes the bacteria inactivate under non-heating environment. In this research, Saccharomyces cerevisiae was used under three kinds of conditions. That is, the pressure level of the underwater shockwave and the causing of the fermentation by the glucose processing. After the underwater shock wave loading and incubating for 24 hours, the sterilization rate was calculated from the number of colonies. As a result, a high sterilization effect of S. cerevisiae in the comparatively low shock wave pressure level was obtained by the glucose processing.
