Abstract:From the comparison of cell inactivation rate and CA and/or SOD activity between wild type and two mutant strains, it was concluded that SOD is an enzyme responsible for ozone resistance. The hypersensitivity of the SOD-negative strain to ozone exposure indicates that L. monocytogenes requires SOD for survival under oxidative stress as a trigger of the detoxification process. Ozone injury and recovery studies showed that L. monocytogenes required RNA and protein synthesis and oxidative phosphorylation for cellular repair from ozone injury. The cell wall was not a site of damage.
