Bacterial strain HV38T was isolated from mangrove soil, which was collected from Thailand. Chemotaxonomic and morphological characteristics were found to be typical of members of the genus Streptomyces. The strain was found to form a distinct phyletic line in the Streptomyces 16S rRNA gene tree and to be closely associated with the type strains of Streptomyces coeruleofuscus CGMCC 4.1667T (98.84 % sequence similarity), Streptomyces chromofuscus CGMCC 4.1451T (98.63 %) and Streptomyces albidoflavus CGMCC 4.1291T (98.56 %). The major menaquinones were identified as MK-9(H8) and MK-9(H10). Its major cellular fatty acids were found to be iso-C14:0, iso-C15:0, anteiso-C15:0, iso-C16:1ω8c, C16:0, anteiso-C16:1ω8c, iso-C16:0 and anteiso-C16:0. The DNA–DNA hybridization values between strain HV38T with S. coeruleofuscus CGMCC 4.1667T, S. chromofuscus CGMCC 4.1451T and S. albidoflavus CGMCC 4.1291T were 32.7 ± 0.9, 21.8 ± 0.3 and 19.9 ± 0.9 %, respectively, which clearly supported the conclusion that they belong to separate genomic species. Cumulatively, the data indicated that strain HV38T represents a novel species of the genus Streptomyces, for which the name Streptomyces ferrugineus sp. nov. is proposed. The type strain is HV38T (=CCTCC AA2014009T= DSM 42152T).
