Actinobacteria of thermal spring Ero (Mongolia)

The article is devoted to the study of actinobacteria in the thermal spring of Mongolia - Ero. In the Ero hot spring, a taxonomic analysis of the microbial community of water, microbial mat and bottom sediments was carried out using the method of high-throughput sequencing for the 16S rRNA gene. It was shown that the largest share of actinobacteria was found in hot spring water (up to 42%), the smallest variety of actinobacteria was found in samples of microbial mats (up to 0.3%). A culture of actinobacteria Nocardia farcinica was isolated from bottom sediments of Ero-19-3 station. The isolated actinobacteria strain is a moderate thermophile with an optimum growth of 45 ° C.
