摘要The winter and summer microbial community structure in sediment samples obtained from the estuaries of the wastewater-polluted River Ou (DO and XO), River Feiyun (DF and XF), and River Ao (DA and XA) in the south of Zhejiang Province in China was determined using 454 pyrosequencing. Sediment samples (DD and XD) were also correspondingly collected near the shore far from the estuaries for comparison. For the above sediments, 294,870 effective sequences were obtained to do the bacterial diversity and abundance determination. In total, 1924, 1517, 2071, 1956, 1995, 1800, 2261, and 2097 operational taxonomic units were obtained at 3 % distance cutoff in the DO, XO, DF, XF, DA, XA, DD, and XD sediments, respectively. Bacterial phylotype richness in DD was higher than the other sediments, and XO had the least richness. The most dominant class in the DA, DD, DF, DO, and XA sediments is Gammaproteobacteria. Deltaproteobacteria is the most dominant one in XD, XO, and XF. Circa 14.4 % sequences in XD were found to be affiliated with the Flavobacteriales order. Characterization of the estuarine sediment bacterial communities indicated that chemical pollution has the potential to decrease the natural variability that exists among estuary ecosystems. However, chemical pollutants did not cause clear bio-homogenization in these estuaries.
