Inactivation of Consortiums of Microorganisms by Air Plasma Jet at Atmospheric Pressure
ABSTRACT
We realize an atmospheric pressure glow discharge air plasma jet at direct current and detect the bactericidal components in plasma jet using optical emission and infrared-absorption spectroscopy. We investigate degree of inactivation of planktonic microorganisms and their consortium after treatment with air plasmajet. We then test the efficiency of plasma inactivation on the natural consortium and find a decreased ability of the surviving microorganisms to form biofilms.
