Freshwater sediment Raw sequence reads. freshwater sediment metagenome

A metagenomic survey of tropical stream sediment (Carrapatos stream sediment, Fe concentration of 21 g/Kg) exposed to metal stress over the course of 300 years by nearby mining activities was conducted, using 16S rRNA tag sequencing. The findings of this study have important implications in the understanding of human settlement activities on microbial community, revealing be complex and associated with distinct metabolisms or life strategies, promoting their maintenance in this environment.
