| 英文摘要 | The influence of compound microbial agents on antibiotic resistance genes (ARGs) in pig manure composting was investigated. The results show that the addition of microbial agents promoted the reduction of total ARGs and the maximum removal efficiencies for absolute abundance (77.2%) and relative abundance (64.5%) were observed in the repeated dose and high dose groups, respectively. Four categories of ARGs declined with the reduction of Firmicutes and Tn916/1545, whereas two categories increased with the proliferation of intl1 and various potential hosts in the composting. The ARG profiles and bacterial communities were shaped by composting stages (mesophilic-thermophilic and cooling-maturation stages) in all groups. However, the addition of microbial agents accelerated the variation of composting stages, and may change the potential ARG hosts which influences the removal of ARGs. Of note, intl1 and two potential pathogens (Mycobacterium and Bacillus) correlated positively to several increased ARGs, implying the possible risks of compost products. |
