In recent years, academic researchers have been particularly interested in a technology known as microbial fuel cells (MFCs), which use microbes to catalyze the conversion of energy held in chemical bonds in organic compounds to electrical energy,. A lot of attention is being paid to alternative electricity-producing methods.
Using renewable bioenergy is one strategy to address the current global warming problem. The use of fossil fuels, notably oil and gas, has grown recently, resulting in a global energy crisis.
This study reviews a diverse community of bacteria in microbial fuel cells, which may be used to remediate industrial effluent. Batik wastewater can be used as a substrate for MFC to generate renewable energy (electricity) and bioremediation of chromium. Today, the presence of the energy crisis and batik industry has reignited interest in MFCs among university academics as a technique to convert biomass to hydrogen without releasing net carbon into the atmosphere. Scientists have known that bacteria may produce electricity by breaking down organic substrates for years.
Various microorganisms in the form of a community or consortium have a higher ability to transfer electrons to the anode and increase the degradation of the organic compound than pure cultures. MFC is an anaerobic bioreactor that transfers chemical energy in organic compound chemical bonds to electrical energy through catalytic reactions of microorganisms. Microbial variety has many functions, and most bacteria can be employed as a biocatalyst in a Microbial Fuel Cell (MFC).
