“…Te external supply of oxygen increased the cathodic reaction rate, which helped to stabilize the potential despite the increased resistance. Te internal resistance of the cell was calculated to be 545.0 Ω. Tis polarization approach scenario and voltage generation trends have been described in a few previous studies [23][24][25].…”

Microbial fuel cells (MFCs) have emerged as a viable method for bioremediation of toxic metals while also producing energy. In this paper, we examine the issue of organic substrate as a source of metabolism for microbe growth in MFC, as well as its significance for metal ion degradation in tandem with energy production. This study focused on the use of commercial sugar as an organic substrate in a single-chamber MFC. The MFC was operated for 27 days, with the highest voltage of 150 mV achieved on day 12, and toxic metal bioremediation efficiencies of 89%, 76.45%, and 89.45% for Pb2+, Cd2+, and Hg2+, respectively. Every 24 hours, the organic substrate (sugar solution) was fed into the cell. This study’s mechanism of metal ion degradation and electron transport is also thoroughly described. In addition, some future views have been highlighted.

The utilization of sediment microbial fuel cell (SMFC) technology presents a paradigm-shifting method for converting the chemical energy obtained from organic and inorganic compounds found in sediment and wastewater substrates into electrical energy. This concept exhibits potential as an environmentally sustainable solution within the future energy sector and presents opportunities for wastewater remediation. This study aims to investigate the influence of anode modification in the SMFC system on generating electrical energy and removing pollutants in landfill leachate. The modification entails synthesizing a nanostructured copper layer on stainless steel (Cu-SS), subsequently compared to the conventional copper (Cu) anode. Results underscore the effectiveness of anode modification, as SMFCs featuring modified anodes exhibit twice the electrical output compared to unmodified counterparts. Modified anode SMFCs yield voltage and current density readings of 615 mV and 17 mA/m 2 , respectively. In addition to electricity generation, the study delves into the SMFC's efficacy in nitrogen compound removal. Experimental results unveil the impressive capability of modified anode SMFCs, achieving 81.02% removal of Biological Oxygen Demand (BOD), while unmodified counterparts reach 76.64%. Furthermore, the removal percentages for ammonia, nitrate, and nitrite compounds within SMFCs equipped with modified anodes are 88%, 51%, and 13%, respectively. This comprehensive analysis underscores the multifaceted benefits of anode modification, amplifying electrical output and enhancing the SMFC's proficiency in nitrogen compound removal, thereby contributing to its potential applications in developing sustainable wastewater treatment and energy generation systems.
