Feasibilities of foam-forming bacteria disintegration by ultrasonic atomization

Abstract

This article presents the feasibilities of bacterial disintegration using ultrasonic atomization. Ultrasound creates acoustic cavitation, which by its effects represents a high gradient of pressure in the form of a shock wave and a local force effect. In our case, the ultrasonic excitation produces a fine micron mist of 3 micrometers. The generated microcavities create a cavitation cloud that is able to disintegrate the foam-forming bacteria or even inactivate bacterial cells. The main goal of the research is the use of ultrasound to disintegrate the foam-forming bacteria during the impact of acoustic cavitation on living cells.
