Summary: In this study, breeding wastewater was efficiently treated using an electroactive microbial community screened from the native microorganisms of the wastewater in microbial fuel cells. The results showed good power generation and high pollutants removal efficiency. The morphology characterization demonstrated the formation of a thick biofilm by the screened electroactive microbial community. Microbial community analysis revealed an increase in microorganisms associated with electricity generation and pollutant degradation, while pathogenic microorganisms were greatly decreased. These findings suggest that the MFC constructed using the screened electroactive microbial community can be a sustainable method for breeding wastewater treatment.

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: Constructed wetlands (CWs) and microbial fuel cells (MFCs) were combined to evaluate their performance in domestic wastewater treatment and electricity generation. The parallel connection of CW-MFCs improved power generation and using three copper wires to connect electrodes enhanced pollutant capture capabilities. The single-column system achieved the highest power density, followed closely by the triple-column continuous system. The zigzag system showed lower power density but had higher removal efficiency of pollutants.

Summary: A catalytic membrane cathode microbial fuel cell (CM-MFC) system was constructed by using a carbon nanofiber-CoFe2O4/polyvinylidene fluoride (CNF-CFO/PM) membrane as the cathode and activated carbon-loaded electrogenic bacteria as the bio-anode. The CM-MFC showed improved catalytic and anti-fouling properties compared to traditional MFC systems. Under optimal conditions, the CM-MFC achieved significant COD reduction and stable output voltage. High-throughput sequencing revealed the presence of enriched electrogenic bacteria coexisting with other anaerobic bacteria, contributing to electron transfer and organics removal. The integration of catalysis and filtration processes in the membrane cathode further enhanced the effluent quality after primary treatment in the anodic chamber.

Summary: Microbial fuel cell (MFC) is a bio-electrochemical system that uses electrogenic bacteria to generate electricity. By utilizing wastewater as feed, MFC can generate clean electricity while treating the wastewater. However, there are challenges in scalability and commercialization of this technology, which can be overcome by the use of ceramics. Ceramics can provide chemical and structural stability as separators, chassis, or electrodes in MFCs, and they are low-cost, eco-friendly, and readily available.

Summary: Two constructed wetland-microbial fuel cell (CW-MFC) systems were connected in series with cathodic aeration to investigate the effects of aeration rate and hydraulic retention time (HRT) on pollutant removal and electricity production in high-concentration wastewater. Results showed that aeration enhanced NH4+-N and TP removal, but had no significant effect on COD removal. Aeration also improved the output voltage and power density of the system, especially in the first stage CW-MFC. Increasing HRT improved pollutant treatment efficiency and power generation performance.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
