Performance of electroactive anaerobic granular sludge under ammonia stress

This study investigated the feasibility of direct interspecies electron transfer (DIET) in enhancing the performance of anaerobic granular sludge (AnGS) under ammonia stress. Microbial community analysis revealed a shift in DIET patterns, transforming from Geobacter - Methanothrix to unclassified genus from family Anaerolineaceae, order Bacteroidales and family Clostridiaceae - Methanosarcina under ammonia stress.
