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.

商业糖作为单室微生物燃料电池底物对提高金属生物修复能源生产的影响

微生物燃料电池 (MFC) 已成为生物修复有毒金属同时还能产生能量的可行方法。在本文中，我们研究了有机底物作为 MFC 中微生物生长代谢来源的问题，以及它对金属离子降解和能量产生的重要性。本研究的重点是在单室 MFC 中使用商业糖作为有机底物。^{MFC运行27天，第12天达到150 mV的最高电压，对Pb 2+}、Cd ²⁺和Hg ²⁺的有毒金属生物修复效率分别为89%、76.45%和89.45%， 分别。每 24 小时，将有机底物（糖溶液）送入池中。本研究还详细描述了金属离子降解和电子传输的机制。此外，还强调了一些未来的观点。
