Abstract

This study aimed to use whey and river sediment microbial fuel cells (SMFCs) to produce electrical potential, which has been investigated rarely in previous studies. In this study, the majority of the microorganisms in the river SMFC mixed culture were Bacteroides and Clostridium. After the voltage and internal resistance were measured, the current and power density were calculated. The power density (279*10-3 mW/cm2 ) and maximum current density (1100*10-6 mA/cm2 ) were determined through computations. Bacteria present in river SMFCs showed the potential to generate electricity without any external mediators. By utilizing organic materials, bioelectricity can be produced affordably and sustainably.

利用河流沉积物微生物燃料电池研究乳清的电势

本研究旨在利用乳清和河流沉积物微生物燃料电池（SMFCs）产生电势，这在以往的研究中很少涉及。在这项研究中，河沙微生物燃料电池混合培养物中的大多数微生物都是乳酸菌和梭状芽孢杆菌。在测量了电压和内阻后，计算了电流和功率密度。通过计算确定了功率密度（279*10-3 mW/cm2）和最大电流密度（1100*10-6 mA/cm2）。河水 SMFC 中的细菌显示出在没有任何外部介质的情况下发电的潜力。通过利用有机材料，可以经济、可持续地生产生物电力。关键词：电势 SMFC 处理乳清河流沉积物 Bull.Chem.Soc.2024, 38(5), 1479-1491.DOI: https://dx.doi.org/10.4314/bcse.v38i5.22
