The characterization of bacterial community compositions and the change in perfluoroalkyl acids (PFAAs) along a natural river distribution system were explored in the present study. Illumina high-throughput sequencing was used to explore bacterial community diversity and structure in sediment polluted by PFAAs from the Xiaoqing River, the area with concentrated fluorochemical facilities in China. The concentration of PFAAs was in the range of 8.44-465.60 ng/g dry weight (dw) in sediment. Perfluorooctanoic acid (PFOA) was the dominant PFAA in all samples, which accounted for 94.2 % of total PFAAs. High-level PFOA could lead to an obvious increase in relative abundance of Proteobacteria, ε-Proteobacteria, Thiobacillus, and Sulfurimonas and the decrease in relative abundance of other bacteria. Redundancy analysis revealed that PFOA played an important role in the formation of bacterial community, and PFOA at higher concentration could reduce the diversity of bacterial community. When the concentration of PFOA was below 100 ng/g dw in sediment, no significant effect on microbial community structure was observed. Thiobacillus and Sulfurimonas were positively correlated with the concentration of PFOA, suggesting that both genera were resistant to PFOA contamination.
