Abstract
Underwater shock wave, generated by the imploding detonation of propane-oxygen mixture, was applied to treatment microbe. We filled the water containing microbe into a stainless steel pipe having inner diameter of 1 0.9 mm, and transmitted the underwater shock waves which have the maximum pressure of about lOOMPa. As microbe of the treatment experiments, Microcystis sp. were used. Although the maximum mortality rate of Microcystis sp. was 99.9% in one day after processing, it turned out that it becomes 100% in one week after processing. The mortality rate became small when the value of the consistency of Microcystis sp. was large.
