“…These electrons, when transmitted through the external circuit, generate a flow, thus producing the electric current [36,37]. The values of the electric current decrease when the organic matter is depleted because the microbes lose their nutrients to carry out their metabolism and release electrons to the medium [38]. Lettuce waste has been reported as substrates in MFCs, generating electrical current peaks of 5.697 ± 0.065 mA, mentioning that the corrosion of the metal electrodes in the last days of the operation of the MFCs influenced the decrease in its current values [39].…”

Currently, two significant problems involve the government, population, and environment: the accelerated increase in organic waste and the need to replace conventional energy with environmentally sustainable energy. The sustainable use of organic waste is being intensely investigated to generate energy plants that produce alternative sustainable electrical energy beneficial to the population at a low cost. The novelty of this research is given by the use of pepper waste as fuel in the generation of bioelectricity, giving added value to these types of waste, benefiting farmers and companies dedicated to the export and import of these fruits, because they will be able to generate their own electrical energy using their own waste at a lower cost. For this reason, this research uses pepper waste as fuel in single-chamber microbial fuel cells manufactured at a low cost as its primary objective. The maximum values of the electric current (5.118 ± 0.065 mA) and electric potential (1.018 ± 0.101 V) were shown on the fourteenth day, with an optimal operating pH of 7.141 ± 0.134 and electrical conductivity of 112.846 ± 4.888 mS/cm. Likewise, a reduction in the COD was observed from 1210.15 ± 0.89 mg/L to 190.36 ± 16.58 mg/L in the 35 days of monitoring and with a maximum ORP of 426.995 ± 8.615 mV, whose internal resistance was 33.541 ± 2.471 Ω. The peak power density was 154.142 ± 8.151 mW/cm2 at a current density of 4.834 A/cm2, and the Rossellomorea marisflavi strain was identified with 99.57% identity.

“…The concept of MFCs was first introduced by Potter in the 1910s, where E. coli was used as the exoelectrogen and only a very weak current was generated . This technology was then silenced for a long time until MFCs were found to be able to operate with wastewater treatment. − A variety of exoelectrogens has been explored for different treatment circumstances .…”

Microbial fuel cells (MFCs) are next-generation electrical devices that harness biochemical resources to simultaneously generate renewable energy and remediate environmental wastewater. To engineer high-performance MFCs, much attention has been paid to anode materials since anodes are pivotal platforms for electroactive microbial (exoelectrogens) adhesion and electron transfer, thereby dominating the overall power output and substrate degradation efficiency. Driven by emerging lowcost and high-performance MFC anodes fabricated from conventional carbon materials and biomass sources, this Review summarizes recent advances in carbonaceous anodes and their compatible exoelectrogens. The fundamental properties of highperformance anodes, including porosity, biocompatibility, and electric conductivity, are compared in detail to associate the exoelectrogen metabolism with device power output and substrate degradation efficiency. This Review may build up a new interface between abio-and biocomponents to accelerate the journey toward cost-effective, high-efficiency, and large-scale MFCs based on carbonaceous materials.
