A novel aerobic streptomycete, strain SCSIO 01248T, was isolated from a sample of deep-sea sediment collected from the northern South China Sea, at a depth of 1632 m. This isolate formed yellow–white substrate mycelium and grey–white aerial hyphae. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SCSIO 01248T was most closely related to Streptomyces radiopugnans R97T (98.8 % sequence similarity), S. macrosporus NBRC 14748T (97.5 %) and S. megasporus NBRC 14749T (97.3 %). The novel strain could, however, be readily differentiated from S. radiopugnans DSM 41901T on the basis of some physiological and cellular chemical characteristics; the level of DNA–DNA relatedness between these two strains was only 40 %. Based on phylogenetic and phenotypic evidence, strain SCSIO 01248T represents a novel species, for which the name Streptomyces nanhaiensis sp. nov. is proposed. The type strain is SCSIO 01248T ( = DSM 41926T = KCTC 19401T = CCTCC AA 208007T).
