Summary: Microbial fuel cell (MFC) is a promising alternative energy system that converts chemical energy into electricity with the help of microorganisms. It consists of electrodes (anode and cathode), catalyst (microorganism), and proton transport/exchange membrane (PEM). MFC's core function is the oxidation of organic substrates and electron transfer, with key factors being microorganisms and electrodes. Besides electricity generation, MFC also finds applications in wastewater treatment, biofuel production, and biosensors.

Summary: This study introduced a novel process, RtESD, using microbial weak electricity to enhance nitrate removal. Results showed that under 0.2 V MWE stimulation, partial autotrophic denitrification was enhanced, leading to improved electron transfer. The study provided a promising method utilizing MWE derived from wastewater to improve the denitrification rate and removal efficiency of nitrate-containing wastewater treatment processes.

Summary: This study investigated the genetic response of microorganisms to ciprofloxacin in sulfur-mediated biological wastewater treatment. It was found that ciprofloxacin induced the microbial SOS response, promoted carbon and sulfur metabolisms, and enhanced energy generation under stress. Additionally, the microbes tended to cooperate under long-term ciprofloxacin exposure. These findings contribute to understanding the response mechanisms of microorganisms to ciprofloxacin and improving antibiotic-laden wastewater treatment.

Summary: Microbial fuel cells (MFCs) have the potential to simultaneously remove contaminants from wastewater and generate bioelectricity as a green and renewable source of energy. However, large-scale applications of these technologies face technical and economic issues related to the fabrication and performance of MFC components. Innovative approaches such as using waste-driven carbonaceous structures and novel fabrication techniques like 3-D printing are discussed to enhance the efficiency and reduce costs of MFCs. Integrations with other technologies and novel applications are reviewed for practical implementation of MFCs in sustainable wastewater treatment.

Summary: A wastewater treatment system utilizing sulfate-reducing and sulfide-oxidizing processes was developed for organic wastewater with high sulfate/sulfide content. The study investigated the impacts of COD/SO42- ratio and hydraulic retention time (HRT) on the removal efficiencies of sulfate, COD, sulfide, and electricity generation. The results showed stable COD and sulfate removal efficiencies of 94.8±0.6% and 93.0±1.3% during the 63-day continuous operation. A power density level of 18.0±1.6 mW/m2 was achieved with a sulfide removal efficiency of 93.0±1.2%. However, sulfide removal efficiency and power density gradually decreased after 45 days, potentially due to sulfur accumulation on the anode.

Summary: A novel integrated biological system consisting of hybrid linear flow channel reactor (HLFCR) and anaerobic sequential batch reactor (AnSBR) was investigated for efficient treatment of tannery wastewater and recovery of sulfur and methane resources. The system demonstrated high feasibility for anaerobic digestion by utilizing single-stage and two-stage HLFCR topologies with different hydraulic retention times (HRT). The full-scale implementation of the system in a medium sized tannery had significant potential revenue from the sale of recovered resources and savings from reduced electricity demand and sludge disposal.

Summary: Wastewater has high energy potential and it is important to recover this energy in microbial fuel cells (MFCs). This study analyzes the electricity production from yeast wastewater in membrane-less MFCs with Cu-Ag cathode. The research shows that pre-oxidizing the cathode material can enhance the oxidation activity of Cu-Ag cathode and increase the electrical energy production.
