Biotechnological utilization of microbial processes normally starts with the discovery, investigation, and understanding of naturally occurring microbial reactions. Biomolecular tools can help us, not only to gain better understanding of protein reactions; they also enable us to influence reaction properties. For efficient practical applications, modern biological techniques allow us to tailor ...

Microbial extracellular electron transfer-based processes are rapidly progressing toward real-world wastewater treatment applications, but their technological progress as an electric power source remains elusive. It is mainly due to low and unstable density high internal resistance of the bioelectrochemical systems. In a recent Energy & Environmental Science article, Bombelli coworkers report b...

Biochemical oxygen demand (BOD) is a widely used index of water-quality assessment. Since bioelectrochemical BOD biosensors require anaerobic conditions for anodic reactions, they are not directly used in aerobic environments such as aeration tanks. Normally, the BOD biosensors are closed-type, where the anode is packed inside a closed chamber to avoid exposure to oxygen. In this study, a novel...

Bioelectrochemical systems provide a promising tool for the copper recovery from heap leaching solutions which usually contain low and high iron concentrations. In this study, role of ferrous ion concentrations, external resistance in removal synthetic sulfuric acid by lab-scale Microbial Fuel Cell (MFC) was investigated good results were obtained copper.
