Abstract
In this study, three single-chamber Microbial Fuel Cells (MFC) were applied for wastewater of each different organic composition (actual wastewater, synthetic lactate containing wastewater, synthetic acetate containing wastewater) to investigate the influence of change in organic composition of acetate and lactic acid. As the result, the effect of the variation in organic composition was considerably different in each MFCs, the influence of MFC of actual wastewater treatment was lower than another MFCs. Furthermore, the changes of microbial community by the variation in organic composition was observed at Bacteroidetes and Proteobacteria at all MFCs. Acetobacterium was suggested to contribute to the lactic acid degradation process at wastewater treatment, and it suggest a retention of a bacteria of symbiosis with the exoelectrogen are the important factor to the performance stabilization of MFC for the wastewater treatment.
