Structure and community assembly of rare bacterial community in sediments of Sancha Lake.

ABSTRACT: To explore the structure and assembly of the rare bacterial community within sediment samples, as well as their responses their responses to environmental influencing factors, we collected surface sediment and overlying water samples from Sancha Lake across four seasons. MiSeq high-throughput sequencing was applied to the V3-V4 hypervariable regions of the 16 S rRNA genes, and the β - Nearest Taxon index (βNTI) was utilized to analyze the bacterial community assembly in the sediment samples. Our findings uncovered abundant bacterial diversity within the sediment samples of Sancha Lake, with 9314 operational taxonomic units (OTUs) identified, encompassing 59 phyla, 198 classes, 279 orders, 447 families, and 758 genera of bacteria. Proteobacteria and Chloroflexi were the dominant rare bacter
