Bacterial and Archaeal Communities within an Ultraoligotrophic, High-altitude Lake in the Pre-Himalayas of the Qinghai-Tibet Plateau.

ABSTRACT: Puma Yumco Lake (PYL) is an ultraoligotrophic freshwater lake that sits an altitude of 5030 m within the Qinghai-Tibet Plateau of China. The bacterial and archaeal diversity of the lake remains poorly understood, despite their potential to inform on biogeochemical cycling and environment-microbial associations in these unique environments. Here, the bacterial and archaeal communities of PYL were investigated using high-throughput sequencing analysis of community 16S rRNA gene sequences. Further, the relationships among dominant taxa and environmental factors were comprehensively evaluated. Bacterial diversity comprised 31 phyla and 371 genera (10,645 operational taxonomic units [OTUs], Shannon index values of 5.21-6.16) and was significantly higher than that of Archaea (five phyla and 24 g
