Abstract

A Gram-positive, aerobic, actinobacterial strain with rod-shaped spores, designated YIM 63158, was isolated from the surface-sterilized roots of L. collected from Yunnan province, south-west China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 63158 belonged to the genus . The closest neighbours were ‘’ KLBMP 1115 (99.9 % 16S rRNA gene sequence similarity), EUM 221 (99.1 %) and DSM 44774 (98.8 %); sequence similarities to other members of the genus ranged from 98.6 to 94.4 %. The chemotaxonomic characteristics, such as the cell-wall diaminopimelic acid, whole-cell sugars, fatty acid components and major menaquinones, suggested that the isolate belonged to the genus . The G+C content of the genomic DNA was 73.3 mol%. On the basis of physiological, biochemical and chemotaxonomic data, including low DNA–DNA relatedness between the isolate and other members of the genus , it is proposed that strain YIM 63158 represents a novel species in this genus, with the name sp. nov. The type strain is YIM 63158 ( = DSM 45301  = CCTCC AA 208081).
