Abstract
Ultra-high pressure underwater shock waves were applied to treatment microbe. The imploding detonation of propane-oxygen mixture was used to generate underwater shock wave in a sample holder an inner diameter of 10.9 mm. We investigated the imploding detonation wave in approximately cone-shaped combustion chamber having maximum inner diameter of 60 mm and generated underwater shock waves of 100 MPa, 50 MPa and 25 MPa at maximum pressure. As microbe of the treatment experiments, dehydrated eggs, or cysts, 0f Artemia salina were used. As a result, there was the case that small percent of hatch ability and it was suggested that pressing speed of underwater shock wave had an influence on Artemia salina.
