The role of norfloxacin(NOR)and sulfamethoxazole(SMX)in mesophilic and thermophilic anaerobic digestion(AD)of pig manure,with respect to methane production and variations in the microbial community and resistance genes,including antibiotic resistance genes(ARGs),class I integrase(intIl),and heavy metal resistance genes(MRGs),was *** results indicated that NOR exerted little influence on the microbial community,whereas SMX negatively affected the acetoclastic *** abundance of two sulfonamide resistance genes(sul1 and sul2),three quinolone resistance genes(qnrS,parC,and aac(6′)-Ib-cr),and intI1 decreased by 2–3 orders of magnitude at the end of thermophilic *** contrast,mesophilic AD was generally ineffective in reducing the abundance of resistance *** to the results of redundancy analysis,the abundance of ARGs was affected primarily by microbial community dynamics(68.5%),rather than the selective pressure due to antibiotic addition(13.3%).Horizontal gene transfer(HGT)through intI1 contributed to 26.4%of the ARG *** archaeal community also influenced the changes in the resistance genes,and ARG reduction was significantly correlated with enhanced methane *** AD presented a higher methane production potential and greater reduction in resistance gene abundance.
