Abstract:

Short-term cavitational treatment (22 kHz, 1.65 W/cm3, 35 W) of the water showed an increase in the amounts of the cells of Bacillus cereus bacteria type that was explained by the process of cell disaggregation usage microscopical investigations. The duration of disaggregation process was 3-5 minutes with gas bubbling during sonication but 30 minutes without gas bubbling during sonication. It was shown an acceleration of disaggregation process under simultaneous action of gas and cavitation by 10 times (synergistic effect).
