Electricity Generation Using Shewanella and Geobacter in Microbial Fuel Cells

Microbial Fuel Cells (MFCs) represent an innovative bioelectrochemical technology thatharnesses the metabolic activities of electroactive bacteria, particularly Shewanella oneidensisandGeobacter sulfurreducens, to generate electricity. These bacteria transfer electrons to an anodewhile breaking down organic matter, enabling sustainable energy production. This paper exploresthe principles behind MFCs, the electron transfer mechanisms of ShewanellaandGeobacter, andtheir practical applications. Experimental results demonstrate their potential for renewable energygeneration in wastewater treatment, agricultural applications, and remote sensing. The study alsodiscusses the challenges of scaling up MFCs, their environmental impact, and future prospects.
