摘要： A novel actinomycete, designated strain NEAU-C151(T), was isolated from soil collected from Mount Song and characterized using a polyphasic approach. Analysis of the 16S rRNA gene sequence indicated that strain NEAU-C151(T) belongs to the genus Streptomyces and exhibited 97.5, 97.4 and 97.4 % similarities to Streptomyces lincolnensis NRRL 2936(T), Streptomyces coacervatus AS-0823(T), and Streptomyces longisporus ISP 5166(T), respectively. The assignment of strain NEAU-C151(T) to the genus Streptomyces was confirmed by chemotaxonomic data: anteiso-C-15:0, C-16:0, iso-C-16:0, C-16:1 (omega 7c) and anteiso-C-17:0 as the major cellular fatty acids; whole-cell sugars contained ribose and glucose; phospholipid profile consisted of diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), unidentified phospholipid (PL), unidentified lipids (L) and phosphatidylinositol mannoside (PIM); the menaquinones were MK-9(H-4), MK-9(H-6), MK-10(H-2) and MK-9(H-8). However, multilocus sequence analysis based on five other house-keeping genes (atpD, gyrB, recA, rpoB, and trpB), DNA-DNA relatedness and phenotypic data showed that strain NEAU-C151(T) could be distinguished from its closest relatives. Consequently, strain NEAU-C151(T) represents a novel species of the genus Streptomyces, for which the name Streptomyces montanus sp. nov. is proposed. The type strain is NEAU-C151(T) (=CGMCC 4.7498(T)=DSM 107808(T)).
