Saccharomyces Cerevisiae (S. Cerevisiae) and Mrakia Frigida (M. Frigida) were deactivated using alternative current dielectric barrier discharge (DBD). The deactivation was done in argon and oxygen plasma under different discharge currents. It has been found that ozone and atomic oxygen play a significant role in the deactivation of S. Cerevisiae and M. Frigida when using DBD discharge, while argon ions are less important in the deactivation of the same microorganisms in argon DBD.
