Summary: After connecting two double-anode microbial fuel cells (MFCs) in series, one MFC experienced decreased electricity generation, while the other was minimally affected. The removal efficiencies varied between the two MFC reactors, with the MFC that generated less power showing higher removal efficiencies. Changes in microbial communities were observed, with an increase in communities related to the degradation of refractory organic compounds and a decrease in communities related to electricity generation in the MFC with reduced electricity generation.

Summary: Quorum quenching (QQ) has been successful in preventing biofouling in membrane bioreactors (MBRs) using isolated QQ bacterial strains. However, the effect of QQ on the microbial population is still not fully understood. This study analyzed the microbial population in MBRs over an extended period under different conditions and found that QQ treatment did not significantly affect the structure and diversity of the microbial community. The research also provided insights into the role of bacterial QQ in reducing MBR biofouling and its underlying mechanisms.

Summary: Microbial fuel cell technology attracts attention for its ability to directly recover electrical energy from organic materials. This study optimized the operating conditions of the MFC using the Taguchi Experimental Design model, with a focus on power density, coulombic efficiency, azo dye removal, and COD removal. The determined optimum conditions resulted in a power density of 177.03 mW/m(2), coulombic efficiency of 7.50%, azo dye removal efficiency of 91.26%, and COD removal efficiency of 21.61%. Pareto analysis revealed that substrate type at the anode had the most significant impact on power density, coulombic efficiency, and COD removal, while catholyte pH had the most significant impact on azo dye removal. The polarization curve determined the maximum power density and internal resistance of the MFC operated under optimized conditions as 145.11 mW/m(2) and 243.30 omega, respectively. Cyclic voltammetry showed distinct anodic and cathodic peaks in the CV curve at -183.2 mV and -181.2 mV, respectively.

Summary: Microbial fuel cell (MFC) sensor has great potential for early warning water toxicity monitoring, but long-term operation may decrease its sensitivity due to dead cell accumulation in the anode biofilm. Exposing the biofilm to toxins repeatedly can lead to microbial community adjustment for higher endurance. Modification of the anodic biofilm can enhance sensitivity, especially for newly formed biofilm with higher live cell ratio.

Summary: Bacterial outer-membrane multi-heme cytochromes (OMCs) can modify heme coupling through mechanical interactions among OMCs by controlling their concentrations. The concentration of OMCs significantly impacts their circular dichroism (CD) spectra and redox property, resulting in a 4-fold change in microbial current production. Overexpression of OMCs increases the conductive current across the biofilm, indicating enhanced inter-protein electron hopping via collision on the cell surface.

Summary: The utilization of sludge mixed liquor in microbial fuel cell and membrane bioreactor (MFC-MBR) coupling system was investigated. The effects of return flow on bioelectricity generation and membrane fouling were studied by designing MFC-MBR coupling systems with different return flow ratios. The results showed that bioelectricity generation was enhanced with the increasing return flow ratio. Additionally, MFC-MBR coupling systems with higher return flow ratios exhibited slower growth of transmembrane pressure and declined absolute value of zeta potential, indicating improved floc-culation of sludge particles and reduced soluble microbial products (SMP) and extracellular polymeric substances (EPS). Bacteroidetes and Chlorobiaceae were found to be more abundant in MFC-MBR coupling systems with higher return flow ratios.

Summary: This study proposed the combination of microbial fuel cell (MFC) with bio-electrochemical enhanced hydrolysis process to simultaneously utilize membrane foulant and generate electricity. The biodegradability of the foulant was revealed through variations in polysaccharides, proteins, humic acid concentrations, and fluorescent compounds in different chambers. Optimized hydraulic retention time improved foulant hydrolysis and enabled efficient utilization of its biodegradable components by MFC. The MFC-MFC system achieved the highest voltage and satisfactory effluent quality at a hydraulic retention time of 1 day. Microbial community structure analysis showed that Proteobacteria, Planctomycetes, and Bacteroidetes were the dominant phyla, with Proteobacteria playing a key role in foulant utilization. This study suggests that MFC hybrid systems have potential for synchronous foulant reuse and energy recovery.
