Abstract
A novel actinomycete, designated KLBMP 1284T, was isolated from the surface-sterilized stems of a coastal halophyte Tamarix chinensis Lour. collected from the city of Nantong, Jiangsu Province, east China. The strain was found to have morphological and chemotaxonomic characteristics typical of members of the genus Streptomyces . Analysis of the 16S rRNA gene sequence of strain KLBMP 1284T revealed that the strain formed a distinct clade within the phylogenetic tree based on 16S rRNA gene sequences and the highest sequence similarity (99.43 %) was to Streptomyces sulphureus NRRL B-1627T. 16S rRNA gene sequence similarity to other species of the genus Streptomyces was lower than 97 %. Based on DNA–DNA hybridization values and comparison of morphological and phenotypic data, KLBMP 1284T could be distinguished from the closest phylogenetically related species, Streptomyces sulphureus NRRL B-1627T. Thus, based on these data, it is evident that strain KLBMP 1284T represents a novel species of the genus Streptomyces , for which the name Streptomyces halophytocola sp. nov. is proposed. The type strain is KLBMP 1284T ( = KCTC 19890T = NBRC 108770T).
