Change of bacterial amount during sonication

The dynamics of the change of microbial amounts in water medium in sonication time was determined. Gases bubbling of different nature into the reaction medium for water disinfection from bacteria under cavitation conditions is proposed in the article. The rate constants of destruction of Bacillus cereus bacteria type in the gas atmosphere are expected. It was determined that the processes microorganisms’ destruction at bubbling of all investigated gases are described by the kinetic equations of the first order.
