Sterilization effect and mechanism exploration of a mode-combination method on Staphylococcus aureus in thick ice layers in a large sealed freezer
Cold-chain transport is a crucial cross-regional transmission pathway for severe acute respiratory syndrome coronavirus 2 and other microorganisms. In this study, the mode-combination method is adopted for sterilization in a 1.138 m3 freezer by mixing effluent gases of NOx and O3 mode air discharges. The mixed gas can effectively inactivate Staphylococcus aureus in 10 mm ice within 3 h, which significantly surpasses O3 gas. Moreover, the inactivation effect of the mixed gas can penetrate deep into ice, contrasting with the surface effect of O3 gas. This disparity is linked to the difference in penetration depth of strong oxidizing long-lived reactive species. This study validates the sterilization efficacy of cold atmospheric plasma in practical cold-chain environment, critical for curbing infectious disease transmission.
