We confirmed that considerable amount of hydrogen peroxide was formed by the ultrasonic irradiation on distilled water with the use of PIEZO-electric ultrasonic generator under the conditions of 550 k cycle per sec., 1500 volts. For killing of the test yeast, Saccharomyces sake No. 3,the mechanical action of ultrasonics by vibration was much more effective than their oxidative one. Many variants which were obtained by treating with ultrasonics were inferior in the activities of glucozymase, catalase, succinic dehydrogenase, α-glycerophosphate dehydrogenase, and alcohol dehydroggenase, but superior in maltozymase activity to the parent strain. Analogous effects were also observed on the variants treated with hydrogen perioxide.
