This study investigated the effects of photooxidative stress and mannitol on the synthesis of OmpC and OmpFporins of Escherichia coli in lake water. The synthesis of OmpF decreased independently of photooxidativestress, whereas the synthesis of OmpC decreased as a consequence of photooxidative stress in lake water. Thus,OmpC synthesis in E. coli was directly affected by photooxidative stress. Mutations in the envZ and pta geneshad no effect on the control of OmpC and OmpF synthesis in E. coli under photooxidative stress in lake water.Mannitol is an antioxidant substance that provides protection from photooxidative stress. In this study, it wasfound that OmpF synthesis decreased independently of photooxidative stress in lake water, whereas decreases inOmpC synthesis were dependent on photooxidative stress in wild type E. coli. OmpC synthesis was regulated byphotooxidative stress via an unknown mechanism.. Mannitol was also found to have a relationship with EnvZ inthe control of porin synthesis
