Bacterial community structure in full-scale mesophilic anaerobic digesters treating cattle or swine manure is determined by substrate type and free ammonia
Author(s): Jonathan Aaron*
Anaerobic Digestion (AD), which is mediated by microorganisms, is a highly effective biological method for the treatment of organic waste and the production of biogas. The primary determinants of bacterial community structure and the potential core and distinctive bacterial populations in manure anaerobic digesters are still not fully understood. Using high-throughput 16S rRNA amplicon sequencing, we examined the changes in bacterial community compositions in 20 full-scale anaerobic digesters processing bovine or swine dung for this study. Free Ammonia (FA) and substrate type appeared to be important factors in shaping the organisation of the bacterial population, according to clustering and correlation analysis. The most significant operational indicators that could be used to relate the bacterial populations in the digesters for swine and cow dung, respectively, were the COD: NH+ 4N.. Read More»
