Abstract
Microbial electrochemical systems (MES) utilize microorganisms to convert chemical energy stored in the organic matter into electrical energy. The microorganisms that can transfer electrons via their metabolic process using a protein network across the cell membrane are referred to as exo-electrogenic or electroactive microorganisms. Electroactive biofilms (EAB) play a crucial role in MES as microbial metabolism in biofilm is coupled with the extracellular electron transfer to the electrode. The formation and functioning of EAB are vital for the performance of MES. Several intrinsic and extrinsic parameters affect biofilm formation. This chapter has summarized electroactive biofilm formation and various mechanisms of electron transfer. Further, the factors that affect biofilm formation are also discussed.
