“…As a result, the MFC bacteria Termincola ferriacetica, Escherichia coli, Desulfuromonas acetoxidans, Geobacter sulfurreducens, and Bacillus subtilis produced an electric current [18]. Candida melibiosica, Pichia anomala, P. polymorpha, Saccharomyces cerevisiae, and Blastobotrys adeninivorans are being recognized as potential catalysts in the MFC [19]. Under fuel cell operation, the microbial composition dependence in a wastewater-fed-batch MFC system was determined using the 16S rRNA gene sequencing.…”

Microbial fuel cells (MFCs) are a cost-effective and environmentally friendly alternative energy method. MFC technology has gained much interest in recent decades owing to its effectiveness in remediating wastewater and generating bioelectricity. The microbial fuel cell generates energy mainlybecause of oxidation-reduction reactions. In this reaction, electrons were transferred between two reactants. Bioinformatics is expanding across a wide range of microbial fuel cell technology. Electroactive species in the microbial community were evaluated using bioinformatics methodologies in whole genome sequencing, RNA sequencing, transcriptomics, metagenomics, and phylogenetics. Technology advancements in microbial fuel cells primarily produce power from organic and inorganic waste from various sources. Reduced chemical oxygen demand and waste degradation are two added advantages for microbial fuel cells. From plants, bacteria, and algae, microbial fuel cells were developed. Due to the rapid advancement of sequencing techniques, bioinformatics approaches are currently widely used in the technology of microbial fuel cells. In addition, they play an important role in determining the composition of electroactive species in microorganisms. The metabolic pathway is also possible to determine with bioinformatics resources. A computational technique that reveals the nature of the mediators and the substrate was also used to predict the electrochemical properties. Computational strategies were used to tackle significant challenges in experimental procedures, such as optimization and understanding microbiological systems. The main focus of this review is on utilizing bioinformatics techniques to improve microbial fuel cell technology.

“…Thus, microorganisms, watermelon-rind residues, and wastewater contributed to generating electricity [28]. Within this context, it is worth mentioning that the presence of sugars such as glucose in wastewater sludge improves the conductivity property of MFCs [29]; in this sense, many species of microorganisms can produce currents in an MFC using glucose as a substrate [30], which serves as a carbon source [31]. This research has an impact because it offers a clean and sustainable energy alternative to the demand for fossil fuels that cause greenhouse gases.…”

Power generation and wastewater treatment are two great challenges for sustainable development. Microbial fuel cells (MFCs) are a sustainable alternative that can generate bioelectricity in the bioremediation process of wastewater. For this reason, the objective of this research was to generate bioelectricity through double-chamber microbial-combustion cell systems from wastewater from the Covicorti Wastewater Treatment Plant (PTARC) in the anodic chamber and electrogenic bacteria such as Stenotrophomonas maltophilia, Acinetobacter bereziniae, and Achromobacteria xylosoxidans in the cathode chamber, respectively. Measurements of the voltage, current, power density, current density, and optical density of the bacteria and biochemical oxygen demand (BOD) were made. In addition, a metagenomic analysis of the wastewater sample was performed. It was shown that the MFC with A. xylosoxidans generated the highest voltage peak (1.01 ± 0.06 V) on day 24, while the MFC with S. maltophilia generated the highest current value (0.71 ± 0.02 mA). The pH levels were slightly alkaline, and the maximum anodic conductivity value was presented by the MFC with A. cerevisiae, with a peak value of 81 ± 2 mS/cm on day 24. On the other hand, a maximum power density and current density of 195,493 ± 4717 mW/m2 and 4987 A/cm2, respectively, were obtained in the MFC with A. xylosoxidans. Finally, the metagenomic analysis identified the predominant phyla of Proteobacteria present in wastewater samples capable of generating electrical energy as Bacillota, Pseudomonadota, Bacteroidota, Actinomyketone, and Campylobacterota.

“…A Microbial Fuel Cell (MFC) is a promising biological technology that uses exoelectrogenic microorganisms' metabolic activity to generate electricity. (Chaturvedi and Verma, 2016) It is a bioreactor wherein the microorganisms such as Geobacter, Shewanella, Pseudomonas and others convert the chemical energy stored in the biodegradable organic matter present in the substrate to electrical energy through the breakdown of the organic matter (Konovalova et al, 2018). Hence, the organic-rich substrate is the fuel to the cell.…”

In recent times, the use of energy resources, particularly non-renewable resources, have increased manifolds due to the ever-increasing global demands. This has led to an increase in depletion of the resources and environmental pollution. Microbial Fuel Cells (MFC) are a new concept that has proved to be the solution to the problem as a green energy resource. The paper focuses on generating electricity from wastewater prepared from kitchen wet waste kept for about 168 hours in an attempt to address the energy crisis while also treating it. A comparative analysis of the sample as prepared and with acetate has been studied and power generation, coulombic efficiency and change in chemical oxygen demand (COD) for wastewater were calculated and also the catalytic effect of acetate was analyzed. It was observed that there was a substantial increase in coulombic efficiency and COD content . A coulombic Efficiency efficiency of 25.29% was obtained for the sample with acetate, whereas, without acetate it was calculated as 9.71%. The maximum power density was obtained from the polarization curves. It was observed that the maximum power density of pure kitchen wastewater was found to be 0.017 mW/m2; however, for kitchen wastewater with acetate, the power density increased considerably to 0.546 mW/m2 at an external resistance of 1Kῼ. Further, the maximum current densities observed were 2.239 mA/m2 and 8.771 mA/m2, respectively. The internal resistance of the constructed prototypes was also determined using the maximum power transfer theorem. In this study, a prototype was constructed and it was found that kitchen waste can be used as a source of electricity generation and leads to a green energy initiative.
