Summary: Microbial variety plays a crucial role in the Microbial Fuel Cell (MFC) as most bacteria can act as biocatalysts. MFC, an anaerobic bioreactor, converts chemical energy in organic compounds to electrical energy through microbial catalytic reactions. Microorganisms in the form of a community or consortium are more efficient in electron transfer and organic compound degradation compared to pure cultures. The use of MFCs for biomass conversion to hydrogen and remediation of industrial effluent, such as batik wastewater, has gained renewed interest due to the energy crisis and environmental concerns.

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: This study examined the use of biosynthesized Cu-Graphene nanosheets in a sulfonated polyethersulfone matrix to fabricate an anti-biofouling proton exchange membrane for microbial fuel cells. The results showed that the presence of Cu, graphene, and biofunctionalities in the membrane's structure improved its hydrophilicity, proton selectivity, and anti-biofouling resistance, leading to higher power generation and better wastewater treatment in the MFC. The modified membranes also exhibited excellent antibacterial activity and were effective in removing organic contaminants from the wastewater.

Summary: Most wastewater treatment plants rely on energy-intensive activated sludge units, but this study introduces a promising alternative called the electrochemical microbial tree (EMT). The EMT uses capillary action to draw organic matter from the wastewater up to an aerial section where microorganisms oxidize it, resulting in high COD removal rates. The EMT also lowers pH and promotes the formation of biofilm, demonstrating its potential as an energy-free wastewater treatment system.
