The disinfection of water from Diplococcus, S.lutea, B.cereus, and Ps.fluorescens bacteria types and the yeast Sacch.cerevisiae via the joint action of gas/US has been investigated. The investigated microorganisms were identified in natural water and wastewater in dominant amounts. The relative ranges of effective cell destruction by combined gas/US action have been established. The most efficient microorganism destruction has been obtained using Ar/US compared to Не/US, СО2/US and О2/US and is accounted for by those gas properties able to affect sonochemical activity.
