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).
一株新的好氧链霉菌，菌株 SCSIO 01248T，从南海北部深海沉积物的样本中分离出来，样本采集深度为 1632 米。该分离株形成黄白色的基内菌丝和灰白色的气生菌丝。基于 16S rRNA 基因序列的系统发育分析表明，菌株 SCSIO 01248T 与放射形棒杆菌 R97T（98.8%序列相似性）、大孢链霉菌 NBRC 14748T（97.5%）和巨大链霉菌 NBRC 14749T（97.3%）最为密切相关。然而，新菌株可以根据一些生理和细胞化学特性与放射形棒杆菌 DSM 41901T 轻易区分开来；这两个菌株之间的 DNA-DNA 同源性水平仅为 40%。基于系统发育和表型证据，菌株 SCSIO 01248T 代表一个新的种，提议命名为南海链霉菌。其模式菌株是 SCSIO 01248T（=DSM 41926T=KCTC 19401T=CCTCC AA 208007T）。
