Abstract: 
The values of еffective rate constants of microorganisms destruction (kd) were compared, depending on the diameter of cells and gas nature bubbling under cavitation conditions. The efficiency of cell destruction under Ar/US is larger by 2–2.5 times compared to He/US, O2/US and CO2/US. Yeast cells were destroyed faster than bacteria (kd (yeast cells) >> kd (bacteria cells)) that is explained by the cells size. The cell stability under cavitational conditions is reversely proportional to the cell diameter. Considering the cell sizes, the presented dependencies of kd = ƒ(dcells) can be successfully used as a standard not only for qualitative determination, but also for evaluating the efficiency of cavitation treatment of water in the presence of O2, CO2, Ar and He.
