Abstract :
Summary form only given. The one atmosphere uniform glow discharge plasma (OAUGDP) is a non-thermal plasma with the classical characteristics of a low pressure DC normal glow discharge during each half cycle, that operates in air (and other gases) at atmospheric pressure. Exposure in a parallel plate version of the OAUGDP has been used to kill foodborne pathogens on surfaces. The objectives of our study were to determine the efficacy of the OAUGDP for inactivation of foodborne pathogens and to evaluate the influence of growth temperature, pH, and culture age on inactivation.
