Role of Microbial Community in Microbial Fuel Cells

Abstract

AbstractThe catalytic activity of oxidation of organic molecules and their conversion into a biofilm is performed by microorganisms using electrical energy that is generated in the microbial fuel cells (MFCs). MFCs are considered to be a novel environmentally sustainable technology, to be used for bioremediation and energy production, since it generates energy from many organic substrates. MFCs technology can assist with have you metal removal and recovery. It has been reported that microbial strains may achieve enhanced power densities, compared to the power densities of the existing mixed community strains. This approach is only being employed on a laboratory scale due to a few constraints such as poor efficiency and low production rates. This chapter discusses the high-power generating bacteria found inside microorganism colonies, production of biofilm, the roles and mechanisms of various microorganisms in energy generation, removal of heavy metal, and electron transport in the fuel cell.KeywordsMicrobial fuel cellsHeavy metalsBacterial speciesBiofilm
