英文摘要	The composting of fresh manure is an effective way to inactivate pathogens and reduce the levels of antibiotics and some antibiotic resistance genes (ARGs) prior to its application on agricultural land as organic fertilizer. However, some ARGs could still exist and even be enriched after composting. This study investigated whether converting composted pig manure into biochar could reduce the dissemination of ARGs into the soil in comparison with a compost amendment. We performed a pot experiment using pakchoi (Brassica chinensis), with two pig manure-based composts and the biochar derived from composted pig manure, as organic fertilizers. The distributions of the antibiotic resistome, mobile genetic elements (MGEs) and bacterial community composition in soils during cultivation were evaluated by high-throughput qPCR and Illumina sequencing. The total ARGs and MGEs abundance in the biochar-treated soils were significantly lower than those in the compost-amended soils during cultivation. The total ARGs abundance in the biochar-amended soils was similar to that in the control soils during cultivation. Thus, the dissemination of ARGs from animal waste to the environment can be effectively mitigated by converting manure into biochar. (C) 2018 Elsevier B.V. All rights reserved.
