Abstract

Sterilization of Bacillus subtilis-contaminated stainless steel dishes via a low-pressure DC glow discharge was investigated using 3% hydrogen peroxide (H₂O₂) and its mixture with argon (Ar). Total inactivation of 10⁷ Bacillus cells was achieved in just 12 minutes using H₂O₂ plasma utilizing ∼10 W power and having sample temperature not exceeding 65°C. The fast sterilization process, under low input power and temperature, through the detoxifying nature of the plasma coupled with the chemical effect of the H₂O₂ makes the discharge facility commercially competitive.
