Abstract

In this study, we studied the bacterial community in 15 estuarine sediments of Poyang Lake using high throughput sequencing. The results showed that the dominant phyla were Proteobacteria (32.1%), Acidobacteria (16.6%), Chloroflexi (14.4%), Nitrospirae (8.8%) and Actinobacteria (6.0%). The dominant genera were norank_Acidobacteria (8.9%) and Nitrospira (8.4%). Based on the difference of the bacterial community structure in sampled estuarine sediments, the five main tributaries of Poyang Lake were divided into the Gan River-Rao River-Xin River group and the Fu River-Xiu River group:the former group had significantly higher abundance of Acidobacteria, Nitrospirae, Gemmatimonadetes and Latescibacteria, while the latter group had significantly higher abundance of Actinobacteria, Bacteroidetes, Firmicutes, Ignavibacteriae and Deltaproteobacteria. The bacterial community structure in sediment of the downstream channel of Poyang Lake had large difference with that in other estuarine sediments, and significantly higher abundance of Chloroflexi, Aminicenantes and Firmicutes was observed. The main environmental factors explaining the variations in phylum abundance were pH and organic carbon, and pH was the main environmental factor leading to the difference of bacterial community structures between Gan River-Rao River-Xin River group and the Fu River-Xiu River group. The above results can help to analyze the element and energy cycling in the estuarine ecosystem of Poyang Lake from the microbial perspective.
