Comparison of microbial communities in thirteen field-scale anaerobic digesters treating different organic wastes
Characterizing the microbial communities is important to understand anaerobic digestion of organic wastes.Substrate type and operating temperature are among the crucial factors influencing the development of microbial populations in digesters.This study aimed to monitor the microbial communities in thirteen field-scale anaerobic digesters treating food waste,animal manure,sewage sludge,or mixed wastes.The field-scale digesters contained diverse microbial populations,whose structures varied according to the substrate type and operating temperature.Eleven bacterial families including Ruminococcaceae and Rikenellaceae were shared by all four substrate types,implying their pivotal roles in AD of organic wastes.Both hydrogenotrophic and mixotrophic methanogens were detected,with the hydrogenotrophic Methanomicrobiales as the most abundant methanogenic order in digesters treating animal manure,sewage sludge or mixed wastes.
