ABSTRACT

Bacteria produces various types of diseases but there are some bacteria which are useful for energy production. Electroactive bacteria were unknown to science until a couple of decades ago. But now the scientists are looking for the natural electricity across the world, even on the ocean floor. It alters entire ecosystems, and may help control the chemistry of the Earth. Some anaerobic bacteria like Geobacter and Shiwenella species has the capability to harness the electricity which are present in the mud, sewage. These are the Electroactive bacteria. By linking bacterial metabolism directly with electricity production, the Microbial fuel cell (MFC) eliminates the extra steps necessary in other fuel cell technologies. It is based on the principle of redox reaction and the natural metabolism of microbes. There are different types of MFCs, but single chamber and two chamber MFC are used in mud power generation.In the MFCs there are two electrodes by which the electrons are transfer to the one anode to another anode.In single chamber MFC both electrodes are kept in one chamber in mud connecting with wires and resister,in two chamber MFC the electrodes are placed in different chambers filled with mud and water connected by the plain salt bridge. MFC act as an energy-saving technology.In other words, bacteria can be used to produce biofuels. Microbial fuel cell essentially is a solution for a renewable energy emitted by bacteria activity that need to be take a further attention , research and development.
