“…Notably, the highest maximum power density was attained with mixed fruit wastes (AFW), followed by the addition of PFW, OFW, and MFW, respectively. The presence of fruit wastes as additives appears to promote bio-augmentation and bio-stimulation, consistent with findings reported by Xu et al (2019) and corroborated by our recent studies on BWW (Xu et al, 2019;Akinwumi et al, 2022). These observations align with the results obtained from the polarization curve, exhibiting high compatibility with the model outcomes and reflecting similar trends in the changes of model responses.…”

“…Consequently, the values obtained in this study were notably higher compared to the 362 mV reported by (Obileke et al, 2021) for PWW operational studies conducted without additives. Furthermore, as depicted in Figure 5 (a-e), the polarization and power curves exhibit three distinct phases: activation losses, ohmic losses, and mass transport limitations, previously elucidated (Akinwumi et al, 2022). In the initial phase, known as the rapid voltage loss region, a consistent decline in MFC voltage aligns with an incremental rise in current density, paralleling the findings of Koffi and Okabe (2020).…”

“…The decline in voltage observed at the onset of power generation can be ascribed to activation losses and substrate diffusion. (Koffi & Okabe;Akinwumi et al, 2022). The initial voltage drop stems from the activation energy required to initiate the oxidation-reduction reaction.…”

“…They accomplish this by converting the chemical energy found in organic or inorganic matter into electricity, harnessing the catalytic (metabolic) activity of living organisms. (Agarry, 2017;Akinwumi et al, 2022). The microbial fuel cell (MFC) system comprises two interconnected chambers: the anode chamber (anaerobic) and the cathode chamber (aerobic chamber), which are separated by a salt bridge typically made of Nafion.…”

Microbial Fuel Cells (MFCs) can simultaneously treat wastewater and generate bioelectricity. This study aimed to optimize operational parameters for treating wastewater from the pharmaceutical industry and harnessing bioelectricity generated from the organic components within the wastewater. The conditions for the bioelectricity generation bioprocess —including time (1-166 days), temperature (25–60°C), pH (4.5–7.5), and additive concentrations (10-50g)—were optimized by the method of Box-Behnken Design (BBD) through the principles of Response Surface Methodology (RSM) incorporated into Design Expert software. The open circuit voltage, current, as well as the physicochemical properties of the wastewater in the MFC were closely monitored. The initial Chemical oxygen demand (COD) and Biochemical oxygen demand (BOD) were 1025 and 1346.17 mg/L. The prominent microorganism in both wastewater and fruit waste samples were Esherichia coli, Staphylococcus species, and Salmonella. At optimized conditions (87 days, 42.5oC, pH of 7.5, and 30 g of additives) the maximum voltage of 895 mV and current of 264 mA were obtained. The result illustrated that fruit waste significantly influenced the generation of bioelectricity as well as the reduction of COD and BOD. The maximum power density generated from pharmaceutical wastewater with no fruit waste was 736.13 mW/m2 while the maximum power densities obtained with the addition of pineapple, orange, mango and combination of all the fruit wastes to the pharmaceutical wastewater were 1610.29, 1355, 759.08 and 2168 mW/m2, respectively. These results illustrate the optimum process conditions which can be explored for bioelectricity generation as well as bio-treatment of industrial wastewater.

“…Their results found that the highest open circuit voltage (820 mV) and maximum power density (994.78 mW/m 2 ) correlated with the highest Coulombic efficiency (32.79%) for COD or the 64.75% efficiency removal of BOD, COD (96.28%) and BOD (98.25%). The Nernst-Monod and bioelectrochemical kinetic models developed by Nernst-Monod-Moser adequately described the bioelectrochemical kinetics, whereas the COD and BOD removal kinetics followed first-order and zero-order kinetics [58]. Meanwhile, Bose et al 2023 evaluated bioelectricity generation and pollution removal over several cycles.…”

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.
