N2 - The diversity and composition of bacterial communities in mudflat and mangrove sediments were investigated under the stresses of endocrine-disrupting chemicals (EDCs) using high-throughput sequencing technique. Bacterial diversity in the original sediments was highest among all samples, followed by non-sterilized and sterilized sediments after 84-day incubation. Proteobacteria were the predominant phylum in both mangrove and mudflat sediments, which accounted for 40–60% of the total tags, followed by Cyanobacteria, Chloroflexi, Planctomycetes and Acidobacteria. Although the total population of bacteria was not significantly declined due to the addition of EDCs, bacterial community structures were considerably altered. The number of bacterial genera promoted or inhibited by EDCs was 288 and 324, respectively. Bacterial genera affected by EDCs varied greatly with the types of sediments and the initial status of bacterial communities. Overall, our results suggested that bacterial community structure in mangrove sediments were closely related to their re-development and responses to EDC contamination.
