A Gram-positively staining, aerobic, non-motile actinomycete, strain GW 12687(T), that formed rose-pigmented colonies and branched substrate and aerial mycelia was studied in detail for its taxonomic position. On the basis of 16S rRNA gene sequence similarity studies, strain GW 12687(T) was grouped into the genus Nonomuraea, being most closely related to Nonomuraea dietziae (97.6 %), Nonomuraea africana (97.1 %), and Nonomuraea kuesteri (97.1 %). The 16S rRNA gene sequence similarity to other species of the genus Nonomuraea was < or =97 %. The chemotaxonomic characterization supported allocation of the strain to the genus Nonomuraea. The major menaquinone was MK-9(H(4)) with minor amounts of MK-9(H(2)), MK-9(H(6)), MK-9(H(0)) and MK-8(H(4)). The polar lipid profile contained the major compound diphosphatidylglycerol, moderate amounts of phosphatidylmonomethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, hydroxy-phosphatidylmonomethylethanolamine, and an unknown aminophosphoglycolipid. Phosphatidylinositol mannosides and phosphatidylinositol were also present. The major fatty acids were iso- and anteiso- and 10-methyl-branched fatty acids. The results of physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain GW 12687(T) from closely related species. Thus, GW 12687(T) represents a novel species of the genus Nonomuraea, for which the name Nonomuraea rosea sp. nov. is proposed, with GW 12687(T) (=DSM 45177(T) =CCUG 56107(T)) as the type strain.
一株革兰氏阳性、需氧、不运动放线菌 GW 12687(T) 被深入研究,因其分类地位。根据 16S rRNA 基因序列相似性研究,菌株 GW 12687(T) 被归为游动放线菌属,与 Dietziae nomonureae(97.6%)、Nonomuraea africana(97.1%)和 Nonomuraea kuesteri(97.1%)最为密切相关。与游动放线菌属其他种的 16S rRNA 基因序列相似性<或=97%。化学分类特征支持将该菌株分配到游动放线菌属。主要的menaquinone 是 MK-9(H(4)),少量的 MK-9(H(2))、MK-9(H(6))、MK-9(H(0))和 MK-8(H(4))。极性脂谱包含主要化合物双磷脂酰甘油、适量的磷脂单甲基乙醇胺、磷脂乙醇胺、羟基磷脂乙醇胺、羟基磷脂单甲基乙醇胺和一种未知的氨基糖脂。磷脂酰肌醇和磷脂酰肌醇也存在。主要脂肪酸为异源和前异源和 10-甲基支链脂肪酸。生理生化试验结果表明,菌株 GW 12687(T)与亲缘关系密切的种在基因型和表型上存在差异。因此,GW 12687(T)代表游动放线菌属的一个新种,命名为游动放线菌玫瑰色亚种 nov. ,其模式菌株为 GW 12687(T)(=DSM 45177(T) =CCUG 56107(T))。
