An actinomycete strain, which was designated 172115(T), was isolated from mangrove soil in Shenzhen, China. Strain 172115(T) fell within the genus Streptomyces in the 16S rRNA gene tree and could be grouped into this genus based on its chemotaxonomic and morphological data. The strain shared the highest 16S rRNA gene sequence similarities with Streptomyces lanatus NBRC 12787(T) (AB184845) (98.29%) and Streptomyces lucensis NBRC 13056(T) (AB184280) (98.26%). The DNA-DNA hybridization values between strain 172115(T) and the two most closely related type strains were low enough to justify the assignment of the strain to a novel species. On the basis of these phenotypic, phylogenetic and chemotaxonomic characteristics, 172115(T) represents a novel species of the genus Streptomyces, for which, the name Streptomyces shenzhenensis sp. nov. is proposed for strain 172115(T) (=CCTCC AA 2011001(T)=DSM 42034(T)).
一株放线菌菌株，被命名为 172115(T)，从中国深圳的红树林土壤中分离得到。菌株 172115(T)在 16S rRNA 基因树中属于链霉菌属，根据其化学分类和形态学数据可归入该属。该菌株与链霉菌属的蓝灰链霉菌 NBRC 12787(T)(AB184845)(98.29%)和产光链霉菌 NBRC 13056(T)(AB184280)(98.26%)的 16S rRNA 基因序列相似度最高，相似度均为 98.29%。菌株 172115(T)与这两个最密切相关的模式菌株之间的 DNA-DNA 杂交值足够低，足以证明该菌株属于一个新的种。基于这些表型、系统发育和化学分类特征，172115(T)代表了链霉菌属的一个新种，建议将其命名为深圳链霉菌，其模式菌株为 172115(T)=CCTCC AA 2011001(T)=DSM 42034(T)。
