Abstract:A sequential microbial fuel cell (MFC) was constructed to investigate indole degradation and simultaneous electricity generation using indole and a mixture of indole + glucose as the fuel. When 250mg/L indole and 500mg/L indole were used as the fuels in the MFC, the maximum voltage outputs were 115,118mV, respectively, and the corresponding average removal efficiencies of indole were 100% and 62%. Moreover, 250mg /L and 500mg/L indole were removed completely in the MFC within 6, 30h. When a mixture of 1000 mg/L glucose + 250mg/L indole was used as the fuel, the maximum power density was 51.2W/m3 in the MFC. Within 10 h, the averaged removal rates of indole and COD in the MFC were 100% and 89.5%, respectively. The MFC could enhance biodegradation of recalcitrant contaminants such as indole in practical applications of wastewater treatment.
