Abstract

A novel actinomycete, designated strain NEAU-C151, 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 belongs to the genus and exhibited 97.5, 97.4 and 97.4 % similarities to NRRL 2936, AS-0823, and ISP 5166, respectively. The assignment of strain NEAU-C151 to the genus was confirmed by chemotaxonomic data: -C, C, -C, C (ω7c) and -C 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), MK-9(H), MK-10(H) and MK-9(H). However, multilocus sequence analysis based on five other house-keeping genes (DBA, B and B), DNA–DNA relatedness and phenotypic data showed that strain NEAU-C151 could be distinguished from its closest relatives. Consequently, strain NEAU-C151 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is NEAU-C151 (=CGMCC 4.7498=DSM 107808).
