研究了铜绿假单胞菌氧控制抗氧化剂烷基氢过氧化物还原酶CF (AhpCF)和过氧化氢酶B (KatB)在生物膜和浮游培养中暴露于H2O2时的作用。AhpCF对生物膜细菌的生存至关重要,而KatB对浮游自由游动生物的生存更为重要。
The role of the Pseudomonas aeruginosa OxyR-controlled antioxidants alkyl hydroperoxide reductase CF (AhpCF) and catalase B (KatB) was evaluated in biofilm versus planktonic culture upon exposure to H2O2. AhpCF was found to be critical for survival of biofilm bacteria while KatB was more important for survival of planktonic free-swimming organisms.
