Electricity Generation by Escherichia Coli from Molasses in a Microbial Fuel Cell

Article excerpt

Background: Microbial fuel cells (MFC) are new technology devices for electricity generation from microbial oxidation of organic substrates. MFC is environmentally-friendly process produces electricity by using bacteria to convert organic waste material into electrical energy. The aim of this investi- gation was to assess the ability of Escherichia coli to produce electricity from molasses in microbial fuel cell system.

Methods: In this study dual chamber microbial fuel cells were constructed with glass and using graphite plates as elec- trodes. The volume of each chamber being 160ml was sepa- rated by a Flemion membrane. Pure culture of Escherichia coli cells was inoculated into MFC. Methyl red was employed as mediator for electron transfer from E. coli to graphite anode electrode. Molasses with a concentration of 3% was used as feed in the anodic chamber. …
