摘要：

Acid in-situ leach uranium (U) mining layers (ML) characterized by anaerobic, oligotrophic conditions, high arsenic (As) concentration, represent an unique but poorly characterized microbial habitat. Herein, autotrophic microbial metabolisms and arsenic detoxification strategies in underground ML (depth >111 m) were revealed through 16S rRNA gene amplicon sequencing and metagenomic analysis. Dissolved organic matter (DOM) content in ML after acid in-situ leach mining was significantly higher than that in non-mining layers (NML). Compared with NML, the arsenite (As(III)) content in ML showed a ...
