Recent progress in electrogenic microbial communities in microbial fuel cells

The depletion of non-renewable energy has led to the development of pollution free energy resources.  Combustion of fossil fuels emits a lot of greenhouse gas like carbon dioxide, which has shown alarming consequences to the environment.  Wastewater treatment and electricity generation have been the major concerns for the last few years [1][2]. Microbial fuel cells (MFCs) is lauded for its potentials to solve both energy crisis and environmental pollution [3]. MFCs are energy conversion devices that simultaneously produce electricity while degrading the wastewater's organic materials[4]. MFCs harvests energy through the oxidation of organic substrates and transform into the electric current with the aid of electrogenic microbes [2]. The recent progress in electrogenic microbial communities in microbial fuel cells is discussed and reported.
