Bacterial diversity and evenness were lower in digesters with better performance. ‘‘Richness” of major bacterial genera was higher in digesters with better performance. Poor-performance digesters almost lacked fatty acid and protein-utilizing syntrophs. Putatively WAS-borne bacteria were more abundant in digesters with poor performance. article i nfo abstract Article history: Process parameters and bacterial populations were investigated in four full-scale anaerobic digesters Received 8 March 2016 treating sewage sludge.
