Abstract：Effects of salinity of the simulated wastewater on power generation and the microbial community structure in the microbial fuel cell (MFCs) were investigated. When the MFC was operated sequentially at NaCl concentrations of 0, 20, 40, 60, and 70 g/L, the maximum voltage outputs significantly decreased from 660 to 130 mV and coulombic efficiency (CE) from 67% to 4%. When the MFC was operated at NaCl concentrations of 40 g/L then 70 g/L NaCl, no obvious electricity was generated after two cycle operations. However, in the absence of NaCl, voltages could be recovered to the maximum value of 630 mV within 60 h in the MFC after the salt shock. In addition, high salinity (> 40 g/L NaCl) reduced significantly the microbial diversity and influenced the microbial community structure.
