Abstract In this study, a novel way to enhance the power-output performance of a Rhodococcus pyridinivorans (HR-1) –inoculated microbial fuel cell (MFC) with salinomycin was demonstrated. In the 5 mg/L salinomycin-treated MFC, the maximum power density and current density was promoted by 63.9 % and 28.1 % times, respectively. Cyclic-voltammetry (CV) analysis revealed that upon the addition of salinomycin the activity of electrochemical substances was enhanced, which resulted in the current-density promotion of the MFC. Salinomycin, as a cationic binding agent that can specifically bind to the channel protein, was responsible for electron transfer from the intracellular level to the micro-organism’s surface. Electrochemical impedance spectroscopy (EIS) results revealed that the internal resistance of the MFC was diminished after treatment with salinomycin, and thus it was speculated that the obstruction posed by the bio-membrane for electron transfer was reduced.

接种食盐红球菌的微生物燃料电池中盐霉素模拟牲畜污水的生物发电

摘要 在这项研究中，展示了一种用盐霉素提高接种吡啶红球菌 (HR-1) 的微生物燃料电池 (MFC) 的功率输出性能的新方法。在 5 mg/L 盐霉素处理的 MFC 中，最大功率密度和电流密度分别提高了 63.9% 和 28.1% 倍。循环伏安法 (CV) 分析表明，加入盐霉素后，电化学物质的活性增强，导致 MFC 的电流密度提高。Salinomycin 作为一种阳离子结合剂，可以与通道蛋白特异性结合，负责将电子从细胞内水平转移到微生物表面。
