Bioelectricity production from microbial fuel using Escherichia coli (glucose and brewery waste).

Microbial Fuel Cell (MFC) is a technology that utilizes bacterial growth in carbon-containing solutions to generate electricity or hydrogen. In MFC aerobic conditions are maintained at the cathode and anaerobic at the anode. The MFC design can be modified to produce hydrogen at the cathode by applying an additional over potential and omitting oxygen from the cathode. A microbial fuel cell (MFC) is a bioreactor that converts chemical energy in the organic compounds to electrical energy through catalytic reactions of microorganisms under anaerobic conditions. MFC generally makes use of organic matter and hence a large number of waste materials rich in organic content can be subjected to MFC for electricity generation. Power output and Coulomb efficiency are significantly affected by the types of microbes used in the anodic chamber of MFC, configuration of the MFC and operating conditions. The main objective of this work was to utilize waste water and waste products rich in ions or organic content which can be used as a potent source to generate electricity using microbes. The waste used in this study represents syrup industry waste and brewery waste. From this work waste can be used to generate electricity at the same time reduce the damage done to the natural environment.
