Valorization of mixed blackwater/agricultural wastes for bioelectricity and biohydrogen production: A microbial treatment pathway.

The management of wastewater and agricultural wastes has been limited by the separate treatment processes, which exacerbate pollution and contribute to climate change through greenhouse gas emissions. Given the energy demands and financial burdens of traditional treatment facilities, there is a pressing need for technologies that can concurrently treat solid waste and generate energy. This study aimed to evaluate the feasibility of producing bioelectricity and biohydrogen through the microbial treatment of blackwater and agricultural waste using a dual-chamber Microbial Fuel Cell (MFC).

Adsorption of Bacteria Extracellular Polysaccharide Substances on the Graphite (002) Surface: A DFT and MD Study.

Understanding the principle of the bacteria-anode surface interaction can enhance electron transfer in microbial fuel cells and aid in antibiofouling. In this article, we investigate the adsorption propensity of common adhesins [-acetylglucosamine (NAG), d-glucose, and alginate] found in microbial biofilms on the surface of unmodified and modified graphite through density functional theory and molecular dynamics simulations. DFT results showed that all the molecules could interact with the graphite surface, with NAG (Δ = 3.
