Streptosporangium nanhuense sp. nov., a novel actinomycete isolated from soil.
A novel actinomycete, designated strain NEAU-NH11(T), was isolated from muddy soil collected from a lake and characterized using a polyphasic approach. The 16S rRNA gene sequence analysis showed that strain NEAU-NH11(T) belongs to the genus Streptosporangium, and was most closely related to Streptosporangium amethystogenes subsp. amethystogenes DSM 43179(T) (99.0 %). Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain NEAU-NH11(T) formed a monophyletic clade with Streptosporangium purpuratum CY-15110(T) (98.3 %) and Streptosporangium yunnanense CY-11007(T) (98.0 %), an association that was supported by a bootstrap value of 80 % in the neighbour-joining tree and also recovered with the maximum-likelihood algorithm. However, the low level of DNA-DNA relatedness allowed the strain to be differentiated from S. amethystogenes subsp. amethystogenes DSM 43179(T), S. purpuratum CY-15110(T) and S. yunnanense CY-11007(T). Moreover, strain NEAU-NH11(T) could also be differentiated from its closest related strains by phenotypic characteristics. Therefore, it is proposed that strain NEAU-NH11(T) represents a novel Streptosporangium species, Streptosporangium nanhuense sp. nov. The type strain of S. nanhuense is NEAU-NH11(T). (=CGMCC 4.7131(T) = DSM 46674(T)).
