    abstract = {Microbial Fuel Cells (MFC) are capable of converting the chemical energy stored in the chemical compounds in a biomass to electrical energy with the aid of microorganisms. A better understanding of the relationship between the microbiological and electrical aspects of fuels cells is needed prior to successful MFC application. MFC constructed employing low-cost materials (salt bridge, graphite electrodes) without addition of any toxic mediators and using glucose (3 g L<SUP>-1</SUP>) as substrate and three different electron acceptors potassium permanganate (KMnO<SUB>4</SUB>), potassium ferricyanide (K<SUB>3</SUB>[Fe(CN)<SUB>6</SUB>]) and potassium dichromate (K<SUB>2</SUB>Cr<SUB>2</SUB>O<SUB>7</SUB>) in the cathode chamber without pH adjustment was assessed in the present study. The results showed that MFC performance with KMnO<SUB>4</SUB> was superior than K<SUB>3</SUB>[Fe(CN)<SUB>6</SUB>] and K<SUB>2</SUB>Cr<SUB>2</SUB>O<SUB>7</SUB>. Maximum voltage generation (OCV) and power density for KMnO<SUB>4</SUB> were 1.04 V and 7.29 mW m<SUP>-2</SUP>. Performance of MFC with K<SUB>3</SUB>[Fe(CN)<SUB>6</SUB>] and K<SUB>2</SUB>Cr<SUB>2</SUB>O<SUB>7</SUB> was much lower with a OCV and power density of 0.71 V; 0.92 mW m<SUP>-2</SUP> and 0.56 V; 0.79 mW m<SUP>-2</SUP>, respectively. Demonstrating that KMnO<SUB>4 </SUB>can be used as an effective cathodic electron acceptor to enhance power output on MFC.}
