Abstract:
:To explore the influence of seasonal and regional environmental factors on the bacterial community composition (BCC) and diversity in the sediments of Lake Bosten, the 16S rRNA gene of sediment bacteria in four samples from the lake center area and the macrophyte-dominated area were sequenced using 454 pyrosequencing. According to the operational taxonomic units (OTUs), diversity index, relative abundance, and redundancy analysis (RDA) of the bacteria, the results showed that (i) the bacterial diversity of the lake center area was lower than that of the macrophyte-dominated area, and it was higher in winter than that in summer as a whole; (ii) seasonal factors and geographical changes had obvious effects on the abundance of dominant bacteria, including Proteobacteria and Firmicutes; (iii) a large number of unclassified bacteria were detected in this study, and the dominant unclassified genera in both lake areas included unclassified Sva0485, unclassified Anaerolineaceae, and unclassified Nitrospiraceae; and (iv) TN and TOC were the main environmental factors influencing the sediment bacterial community in Lake Bosten, as determined by RDA analysis. The study provides a reference for the in-depth understanding the impact with the change of time and space on sediment microbes in Lake Bosten.
