Streptomyces shenzhenensis sp. nov., a novel actinomycete isolated from mangrove sediment.

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)).
