Abstract: Electricity generation from an Air Cathode Microbial Fuel Cell (ACMFC) was investigated in treating real mango pulp waste water. In this study novel ACMFC with combined advantages for simultaneous waste water treatment and energy recovery. ACMFC was operated in batch mode with various external resistances. The mango pulp waste water varied concentration in the range of 50,000 mg COD-L to 1,60,000 mg COD-L. At pH range of 6.5–7.2, the cathode open circuit potential (OCP) was achieved as 1.18 V. The maximum voltage obtained was 1.133 V, with an overall chemical oxygen demand (COD) removal of 95 %. To estimate the performance of the ACMFC, the electro chemical measurements were carried out these results showed that the air cathode microbial fuel cell produced stable power and a high CE 31.09 %, making it useful for treatment of actual wastewaters. High power density and successive performance as a power generator was characterized based on polarization behavior. The results of recent studies suggest that in future ACMFCs will be of practical use will become a preferred option among sustainable bioenergy processes.
