The prevalence of Atribacteria affiliated with JS1 in the sediment core of Lake Sayram, the largest alpine lake, China

Atribacteria play an important role in global carbon cycling. Little is known, however, about the Atribacteria communities found inalpine lakes. The presence and diversity of Atribacteria in the sediment core of alpine Sayram lake in China were investigated usingIllumina MiSeq sequencing in this study. According to the findings, Atribacteria affiliated with JS1 were dominant in the sediment coreof Sayram Lake, with a relative abundance of 0.19 to 10% (average 3.75%) of all bacterial sequences. Furthermore, the relativeabundance of Atribacteria associated with JS1 increased with sediment depth. As a result, this study significantly contributes to ourunderstanding of Atribacteria community habitat.
