| Abstract |
The role of the Pseudomonas aeruginosa OxyR-controlled antioxidants alkyl hydroperoxide reductase CF (AhpCF) and catalase B (KatB) was evaluated in biofilm vs. planktonic culture upon exposure to hydrogen peroxide. AhpCF was found to be critical for survival of biofilm bacteria while KatB was more important for survival of planktonic free-swimming organisms. |
