Electrical energy generation can be achieved in microbial fuel cells (MFCs) through the catalytic action of microorganisms which canoxidize organic matter and convert it into a biofilm. In MFCs, the exoelectrogens play a crucial role. MFCs is eco-friendly promisingtechnology that produces electricity from various organic substrates. It is a novel and environmentally friendly approach for bioremediationand sustainable electricity production. The fact that heavy metals contributing adversely to the environmental pollution thus the microbialfuel cell technology has a solution for this as well, performing the removal and recovery of heavy metals by using both single and doublechamberedMFCs. Many studies show that the new strains of microbes can produce power densities individually as high as strains frommixed communities. However, the implementation of this technology is just limited to the laboratory scale because of a few challenges likelow efficiencies, low production rates. This review article focuses an introduction about the role and mechanism of different microorganismstowards energy production, biofilm formation, high power producing microbes inside the microorganisms, the electron transfer mechanismto the electrodes and vice-versa and the removal of heavy metals.
