英文摘要	Elevated arsenic (As) in groundwater is an urgent environmental problem that has caused serious endemic diseases in Datong basin, China. The fate and toxicity of As are generally regulated by microbial As metabolic processes. However, little is known about the microbial community and As metabolism in Datong basin. Herein, the microbial community structure and As metabolism genes in four wells with different levels of As concentration in Shanyin county were investigated using metagenomics approach. The results showed that the presence of As influenced the microbial communities, and Rhodococcus genus was significantly enriched in elevated As wells. As resistance genes were dominant from low to high As containing wells, and As efflux genes such as arsB and acr3 were positively correlated with As concentrations, suggesting that microbes tend to pump As out of the cell as a strategy for As detoxification. Other environmental factors including oxidation-reduction potential (ORP), total organic carbon (TOC), sulfate, and temperature also played a role in shaping the microbial community structure and As metabolic processes.
