Article Synopsis
- The study investigates how antibiotic resistance genes (ARGs) from swine manure are transferred to biogas residue and then to soil when the residue is used as organic fertilizer.
- Despite a reduction in ARGs (43% absent) after anaerobic digestion, some ARGs (9%) were still introduced into the soil.
- The bacterial community in the soil returned to its original state in 60 to 90 days, indicating that the presence of ARGs may not significantly alter the overall microbiome.
The problem of antibiotic resistance genes (ARGs) caused by heavy metals has attracted extensive attention of human beings. Zn, a widely used feed additive, has a very high residue in swine manure, but the distribution characteristics of ARGs imposed by Zn in anaerobic digestion (AD) products are not clear. In this study, the behaviour of mobile genetic elements (MGEs), bacterial community, and their association with ARGs were determined in the presence of 125 and 1250 mg L Zn in AD system of swine manure.

Due to carbon-based materials' good adsorption capacity for heavy metals, graphene and graphene oxide have great potential to reduce ARGs abundance in the environment with copper pollution. To figure out the mechanics, this study investigated the effects of graphene and graphene oxide on the succession of ARGs, mobile genetic elements (MGEs), heavy metal resistance genes (HMRGs), and bacterial communities during copper-contained swine manure anaerobic digestion.
