AIMS To investigate the effect of gas composition on the sensitivity of Bacillus pumilus spores to gas plasmas. METHODS AND RESULTS Inert gas plasmas, oxygen-based plasmas and various moisturized air plasmas were used to inactivate B. pumilus spores in low gas pressure of 50 Pa. Although the treatment temperature did not exceed 55 degrees C when exciting these plasmas, spore survival varied widely depending on the composition of the gas feed. Higher spore mortality was acquired by inert gases… CONTINUE READING
