“…EET in MFC systems includes direct electron transfer and mediated electron transfer. Several strains, such as Geobacter and Shewanella , can transfer electrons directly to the anode surface via intricate networks of outer membrane cytochromes [ 100 , 101 ]. However, more strains need redox mediators for electron transfer due to the lack of electrochemically active surface proteins [ 102 ].…”

The microbial fuel cell has been considered a promising alternative to traditional fossil energy. It has great potential in energy production, waste management, and biomass valorization. However, it has several technical issues, such as low power generation efficiency and operational stability. These issues limit the scale-up and commercialization of MFC systems. This review presents the latest progress in microbial community selection and genetic engineering techniques for enhancing microbial electricity production. The summary of substrate selection covers defined substrates and some inexpensive complex substrates, such as wastewater and lignocellulosic biomass materials. In addition, it also includes electrode modification, electron transfer mediator selection, and optimization of operating conditions. The applications of MFC systems introduced in this review involve wastewater treatment, production of value-added products, and biosensors. This review focuses on the crucial process of microbial fuel cells from preparation to application and provides an outlook for their future development.

“…Accordingly, two main types of MFCs have been reported, fuel cells with electron transfer mediators and fuel cells with direct electron transfer. 7 The most commonly used microorganisms in direct electron transfer based MFCs are Shewanella putrefaciens , 8 Geobacter sulfurreducens , Geobacter metallicreducens , 9 Aeromonas hydrophila , 10 and Rhodoferax ferrireducens . 11 Both extracellular electron transfer methods allow to determine conversion efficiency, yet depending on conversion efficiency is inadequate to determine the MFC behavior as it does not sufficiently explain the energy generation mechanism.…”

Plants microbial fuel cells (PMFC) is novel sytem that generates renewable, clean, and sustainable electricity with minimal environmental impact. However, PMFC has limitations in power generation and current density, since its production values is lower than other renewable technologies. Different studies show that the highest limitation for energy generation through MFC is the high resistivity of the cathode, and the solution is to replace the metallic electrodes with non-metallic materials to obtain a better performance, however, the application of these materials requires complex interdisciplinary work. This study conducted three experimental tests using metallic electrodes for the extraction of electrons and combined a black earth substrate with different natural materials, types of plants, and water to determine their influence in the increment of the electric power output.
