Inactivation of multidrug-resistant pathogens and Y. enterocolitica with cold atmospheric pressure plasma on stainless steel surfaces

The use of cold atmospheric plasma (CAP) is a new nonthermal decontamination method. Plasma is the fourth state of matter and includes a lot of different bactericidal species such as NO, NO2, N2O, CO, CO2, H2O2 and ozone [1, 2]. Plasma is generated by applying an electric field to a working gas, in our study to the inexpensive ambient air. The generated plasma-species cause oxidative stress and damage bacterial cells [3]. If the amount of reactive species exceeds the capacity of cellular repair mechanisms, cell death occurs.
