Abstract：
:The effect of mesophilic anaerobic digestion (AD) on the resistome profile of manures from two different dairy farms was evaluated using a metagenomic approach. A total of 187 unique Antibiotic resistance genes (ARGs) for 17 different classes of antibiotics were detected in raw (undigested) manures. The results indicate that regardless of the origin of the dairy manure, mesophilic AD was capable of reducing or enriching the relative abundance of some ARGs. The main driver of these changes was strongly correlated with the evolution of the microbial community during the AD process. Putative ARG hosts were suggested by analyses of the co-occurrence of microbial groups and ARGs. Finally, network analyses revealed that mesophilic AD could also reduce the co-occurrence of different groups of ARGs potentially located in the same genetic elements. Our results provide valuable insights into the microbial mechanisms driving the diversity and abundance of ARGs during mesophilic AD.
