Saxaul (Haloxylon ammodendron) is a plant with a wide ecological range that forms forests in Mongolia often used as pastures for camels. Actinomycetes were isolated from the soils of the saxaul forest using selective isolation methods. According to the results of phylogenetic analysis based on the sequences of the 16S rRNA gene fragment, it has been established that the obtained isolates belong to the Streptomyces genus. According to the taxonomic position, strains (M41; M42; M 43; C 4-46; C 4-47; C 4-50; M44; C 5-54; C5-60 and C 5-63) demonstrate a high level of similarity (99.20- 100 %) of 16S rRNA gene sequences with type strains of the following species: S. fradiae, S. huasconensis, S. coeruleoprunus, S. tendae, S. rubrogriseus, S. malachitofuscus, S. flavoviridis S. pilosus, S. caelestis, S. azureus, S. fulvissimus, S. microflavus, S. griseussubsp. griseus, S. anulatus, S. cyaneofuscatus, S. luridiscabiei, S. halstedii, S. fulvorobeus, S. pratensis, S. setonii, S. anulatus, S. pratensis, S. caelestis and S. azureus.
