Microbial communities from contaminated river sediment (the River Calcaieu, LA, USA) Metagenome

A total of five communities (DP, DPB, B, B33d, and B43d metagenomes) were sampled. First, three microbial communities were developed for over three years in laboratory bioreactors from the contaminated river sediment inoculum: 1) one with benzalkonium chlorides (BACs, a family of QACs) as a sole carbon and energy source (B community), 2) one with BACs plus dextrin/peptone (DPB community), and 3) a dextrin/peptone-fed one (DP community, control). In parallel, after the substrate of the DP community was replaced with BACs, the microbial communities were sampled at day 33, 4) B33d community, and day 43, 5) B43d community.
