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

An actinomycete strain, which was designated 172115T, was isolated from mangrove soil in Shenzhen, China. Strain 172115T 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 12787T (AB184845) (98.29%) and Streptomyces lucensis NBRC 13056T (AB184280) (98.26%). The DNA–DNA hybridization values between strain 172115T 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, 172115T represents a novel species of the genus Streptomyces, for which, the name Streptomyces shenzhenensis sp. nov. is proposed for strain 172115T (=CCTCC AA 2011001T=DSM 42034T).
