Streptomyces xiangluensis sp. nov., a novel actinomycete isolated from soil

A novel actinomycete, designated strain NEAU-LA29(T), was isolated from soil collected from Xianglu Mountain and subjected to a polyphasic taxonomic study. Based on a polyphasic taxonomic approach comprising chemotaxonomic, phylogenetic, morphological and physiological characterisation, the isolate has been affiliated to the genus Streptomyces. 16S rRNA gene sequence analysis showed that the isolate is closely related to Streptomyces vastus JCM4524(T) (98.8% identity) and Streptomyces cinereus DSM43033(T) (97.9%). However, multilocus sequence analysis based on five other house-keeping genes (atpD, gyrB, rpoB, recA and trpB) and low DNA-DNA relatedness values enabled the strain to be differentiated from these closely related species of the genus Streptomyces. Thus, strain NEAU-LA29(T) is concluded to represent a novel species of the genus Streptomyces, for which the name Streptomyces xiangluensis sp. nov. is proposed. The type strain is NEAU-LA29(T) (=CGMCC 4.7466(T)=DSM 105786(T)).
