Microbial response of mangrove microbiome to BaP and nitrate contamination

Microbial communities harbor keystone taxa, which are drivers of microbiome structure and functioning. However, the characterization and manipulation of such taxa is a major challenge due to the complexity of microbial communities and rapid turnover in both time and space. Here, mangrove sediment microcosms were set up as reductive experimental models to trigger and track the turnover of keystone taxa driven by changing environmental factors to address this challenge. Based on BaP-contaminated and (or) nitrate-added microcosms, shotgun metagenomic and 16S rRNA gene sequencing were launched.
