Feasibility of in-situ bioelectrocatalytic computation to implement simultaneous nitrogen removal of anaerobic digestate and biogas upgrading Raw sequence reads

A two-chamber bioelectrochemical system was constructed to investigate the feasibility of bioelectrocatalysis regulation to enhance simultaneous nitrogen removal from anaerobic digestate and biogas upgrading. The key mechanisms of the bioelectrocatalytic process in inducing the cathode/anode biofilm development and the multi-routes of carbon/nitrogen metabolisms were elucidated. The changes in key microbial community structure at the different stages were investigated to disclose the potential functionality of bioelectrocatalytic regulation in the enrichment of electroactive microorganisms as well as the simultaneous efficient nitrogen removal and CO2 electromethanogenesis. Our current work provides a beneficial supplement to the conventional anaerobic digestion technology for further enhancing simultaneous nitrogen removal of anaerobic digestate and biogas upgrading.
