Abstract

A novel filamentous Actinobacterium, designated strain FXJ1.1311, was isolated from soil collected in Ngari (Ali) Prefecture, Qinghai-Tibet Plateau, western PR China. The strain showed antimicrobial activity against Gram-positive bacteria and . Results of phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FXJ1.1311 belonged to the genus and showed the highest sequence similarity to DHS C013 (98.04%). Morphological and chemotaxonomic characteristics supported its assignment to the genus . The genome-wide average nucleotide identity between strain FXJ1.1311 and DHS C013 as well as other type strains was <82.2 %. Strain FXJ1.1311 also formed a monophyletic line distinct from the known species in the phylogenomic tree. In addition, physiological and chemotaxonomic characteristics allowed phenotypic differentiation of the novel strain from . Based on the evidence presented here, strain FXJ1.1311 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is FXJ1.1311 (=CGMCC 4.7383=DSM 104975).
