Cold Plasma Inactivation of Bacillus cereus and Bacillus anthracis (Anthrax) Spores

摘要: Bacillus spores represent one of the most resistant organisms to conventional sterilization methods. This paper is focused on inactivation two species, cereus and anthracis, using atmospheric-pressure dielectric-barrier-discharge (DBD) plasma. Spores treated in liquid or air-dried a solid surface were effectively inactivated within 1 min DBD plasma treatment at discharge power 0.3 W/cm2. Results series model experiments show that neutral reactive oxygen species UV radiation play dominant role spores. We also 45 s placed inside closed plastic envelopes permits up 7 log reduction viable
