摘要： A novel actinobacterium, designated strain NEAU-SW11(T), was isolated from soil collected from Binxian, Heilongjiang province, north China. The isolate was found to have chemical and morphological properties of the genus Streptacidiphilus, with the highest sequence similarities to Streptacidiphilus anmyonensis JCM 16223(T) (98.1 %), Streptacidiphilus jiangxiensis JCM 12277(T) (97.8 %), Streptacidiphilus melanogenes JCM 16224(T) (97.6 %) and Streptacidiphilus rugosus JCM 16225(T) (97.4 %) and it phylogenetically clustered with these four strains. The cell wall contained LL-diaminopimelic acid as the major diamino acid and the whole-cell hydrolysates were rhamnose, ribose, glucose and galactose. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside and two unidentified phospholipids. The predominant menaquinones were MK-9(H-8) and MK-9(H-6). The major fatty acids were C-16 : 0, anteiso-C-17 : 0, C-14 : 0 and C-15 : 0. The DNA G+C content was 71.0 mol%. However, DNA-DNA hybridization, physiological and biochemical data showed that strain NEAU-SW11(T) could be distinguished from its closest relatives. Therefore, strain NEAU-SW11(T) represents a novel species of the genus Streptacidiphilus, for which the name Streptacidiphilus monticola sp. nov. is proposed. The type strain is NEAU-SW11(T) (= CGMCC 4.7427(T) = DSM 105744(T)).
