This paper summarises different methods used for the Electrical power generation using microorganisms in Microbial Fuel Cell (MFC), where power generation is done in a microbial environment. Microorganisms are used as catalysts to degrade the supplied source effectively. This bioelectricity production is carried out in an enhanced way in a pollution-free environment. This paper addresses different aspects of electricity generation with the help of microorganisms. Various types of Microbial fuel cells have been described based on their constructional details. One of the different power generation methods is wastewater treatment. Also, hydrogen is generated in this environment, which can be used in fuel cells. Different factors and catalysts used to produce bioelectricity are identified and analyzed. Finally, the power produced in those methods had been compared, and the best method is cited.

Microbial fuel cells (MFCs) set a new trend of converting chemical energy or bio energy to electricity from wastewater (domestic and industries) at the same time removal of chemical oxygen demand (COD) from the wastewater. Electrical energy generated from microbial fuel cell could be used for small electrical device example biosensors. The main components of MFCs are the anode, and the cathode salt bridge. It contains an anode chamber and a cathode chamber which separate electrodes for the production of electricity, using wastewater in an anaerobic chamber helps grow native microorganisms. Adding substrates increases productivity of the electrons that are moving from the anode chamber to the cathode chamber by help of the salt bridge. Bioreactors based on power generation in MFCs are a new approach to wastewater treatment. Power generation and current is modulated in this system. If it is optimised, MFCs would prove to be new method to offset wastewater treatment plant operating costs.
