Inactivation of Microorganisms on Plane Surfaces by a Dielectric Barrier Discharge

Abstract

Inactivation of spore microorganisms on a dielectric surface by a dielectric barrier discharge with plane electrodes was studied experimentally. It is shown that, at an average specific discharge power of 0.3 W/cm3 and exposure time of 0.5–60 s, the degree of inactivation amounts to three orders of magnitude and depends weakly on the exposure time.
