鄱阳湖7个河口水体中细菌多样性和组成特征
Bacterial diversities and compositions in seven different estuarine water columns of Poyang Lake
摘要
Abstract
In this study, we analyzed environmental factors of seven different estuarine water columns of Poyang Lake (Gan, Fu, Xin, Le’an, Chang, Rao, and Xiu River), and the bacterial community compositions in these different estuarine sediments were analyzed using the 16S rRNA gene targeted metagenomic approach. Our results showed that Le’an River had the highest total nitrogen content, and Xin River had the highest total phosphorus content. For the bacterial richness and diversity in these seven different estuaries, we found that Le’an, Xiu and Rao rivers showed the higher bacterial richness than other estuarines. Xiu, Chang and Rao rivers showed higher bacterial diversities than others. Bacterial composition analysis indicated that Proteobacteria phylum was dominant in all water samples, followed by Actinobacteria and Bacteroidetes. At the class level, all samples were numerically dominated by members of the Betaproteobacteria, Alphaproteobacteria and Actinobacteria. Furthermore, according to the Spearman’s correlation analysis, we found that there were signiifcant negative relationships between the Chao1 species richness index and pH. Besides, total nitrogen and ammonia concentrations showed signiifcant positive effect on bacterial community richness.关键词
