- aggregation title "A bioelectrochemical system in anaerobic digestion: stabilization and remediation".
- aggregation abstract "Anaerobic digestion (AD) is an established technology for energy recovery from complex organic waste. Excessive organic loading or influent salinity can sometimes disrupt its functioning. In past studies, enhanced biogas production was found upon introducing a bioelectrochemical system (BES) in the anaerobic digester. Here we evaluated the impact of a BES on the anaerobic digestion of molasses. Lab-scale anaerobic digesters were operated in the presence or absence of electrodes, to evaluate the stabilizing capacity of a BES in AD. Methane production declined in the reactors without electrodes, yet remained stable in the reactors with electrodes, indicating a stabilizing effect. After 91 days of operation, the electrodes were introduced in the failing AD reactors in order to evaluate their remediating capacity. Immediately after introduction of the electrodes, methane production increased. Although a current was generated in the BES operated in closed circuit, contrarily to earlier studies which typically lacked a control, no direct effect of applied potential or current density was observed. Microbial community analysis revealed the importance of Methanosaeta sp. on the electrodes. This study demonstrated that a BES can remediate AD systems which exhibited process failure. However, the absence of a clear link between current density and electrode potential in the BES and the stability of the AD process indicates that likely biomass retention on the electrodes is the main cause of the observation.".
