Electricity Optimization in Microbial Fuel Cell of Distillery Wastewater, Vermicompost and Escherichia coli

摘要

Power generation through microbial fuel cell (MFC) is a promising and efficient alternative in the current global energy crisis. In the present investigation, same idea is used for electricity production utilizing Distillery wastewater, vermicompost and Escherichia coli. Experimental results showed that MFC using distillery wastewater gave highest electrical output of 699 mV after 60 h of operation while the cell using vermicompost worked inadequately as it generated electricity upto 131 mV only. On the other hand, E. coli functioned moderately with a maximum output of 456 mV. The operating parameters like pH, oxygen flow rate and substrate concentration were optimized in the MFC consisting of batch anode solution and continuous mode of cathode operation.
