Ozone Sensitivity and Catalase Activity in Pigmented and Non-Pigmented Strains of Serratia MarcescensDOI: 10.2174/1874285801711010012 Keywords: Catalase, oxyR, ozone, pigment, peroxide, prodigiosin, Serratia Abstract: Ozone exposure rapidly leads to bacterial death, making ozone an effective disinfectant in food industry and health care arena. However, microbial defenses may moderate this effect and play a role in the effective use of oxidizing agents for disinfection. Serratia marcescens is an opportunistic pathogen, expressing genes differentially during infection of a human host. A better understanding of regulatory systems that control expression of Serratia’s virulence genes and defenses is therefore valuable
