Abstract

Bacillus cereus is a gram positive, rod shaped, and most abundant bacteria in the nature. In this paper, we intended to focus on the inactivation and morphological and physiological changes of the bacillus cereus with various time periods of atmospheric pressure dielectric barrier discharge (APDBD) plasma exposures. Inactivation, morpho-physiological changes were observed by scanning electron microscope (SEM) in untreated and plasma treated bacterial cells with different time intervals of plasma. Experimental results proven that argon (neutral) gas and radiation of the plasma play an important role in the inactivation of bacterial cells (B. cereus). By these results, very less time of plasma exposure is enough to inactivate the bacterial cells in any surfaces in the environments.
