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: Microbial fuel cells (MFCs) are power generation devices for sustainable energy, and a mini autonomous biosensor (MAB) based on MFCs has been designed for detecting hexavalent chromium in wastewater. Results show that MAB has the potential for simultaneous electricity production and hexavalent chromium detection, with conductive silver glue as anode electrode feasible for detection.

Summary: This study presents a novel approach combining phytoremediation and bio-electrochemical technology to remove Cr(VI) from wastewater using an Acorus calamus L. constructed wetland microbial fuel cell (CW-MFC). The planted CW-MFC showed high efficiency in removing Cr(VI), and the power generation was improved with the addition of low concentrations of Cr(VI). The main removal pathways of Cr involved bio-electrochemical reduction and plant uptake. This research provides valuable insights for the practical application of CW-MFC in Cr(VI)-containing wastewater treatment.

Summary: This study focused on treating saline tannery wastewater using UMFC, achieving high removal rates of chemical oxygen demand and total suspended solids. The optimal organic load for treatment and energy production was found to be 1.8 gCOD/L, with significant chromium bioaccumulation. Analysis of bacterial community in the UMFC revealed the presence of electrogenic halophilic strains, contributing to the efficacy of the treatment process.

Summary: A microbial fuel cell (MFC) sensor was developed to monitor wastewater containing high concentrations of bisphenol A (BPA). The voltage output from the MFC sensor was used to determine the toxicity of contaminants in wastewater. The MFC sensor exhibited a significant decrease in voltage output in BPA-containing wastewater, and the detection performance could be recovered using sodium acetate as a regeneration solution.

Summary: The operation of a scaled-up air-cathode microbial fuel cell (MFC) using synthetic wastewater in continuous flow indicated that optimal performance was achieved under a hydraulic retention time (HRT) of 12 hours, resulting in higher electricity generation and wastewater treatment efficiency. However, due to anaerobic conditions, the MFC was unable to remove nutrients. The MFC also showed potential in reducing wastewater toxicity, as demonstrated by an acute toxicity test using Lactuca sativa.
