A pale pink, Gram-reaction-negative, non-motile, aerobic bacterium, designated MC 3624T, was isolated from a tundra soil near Ny-Ålesund, Svalbard Archipelago, Norway (78° N). Growth occurred at 10-37 °C (optimum 25-30 °C) and at pH 6.0-9.0 (optimum pH 8.0). The predominant fatty acids were C16 : 0 (17.7 %), C18 : 1ω7c 11-methyl (13.4 %), summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) (10.1 %) and summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c) (38.3 %). The major respiratory quinone was ubiquinone-10, and the main polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and an unidentified aminolipids. The DNA G+C content was 68.9 mol%. Carotenoids of the spirilloxanthin series were produced. The nearest neighbour to the novel strain was Roseomonas wooponensis WW53T (94.36 % 16S rRNA gene sequence similarity). On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain MC 3624T represents a novel species of the genus Roseomonas, for which the name Roseomonas arcticisoli sp. nov. is proposed. The type strain is MC 3624T (=CCTCC AB 2014278T=LMG 28637T).
从挪威斯瓦尔巴群岛新奥尔松附近（北纬78°）的苔原土壤中分离出一株浅粉色、革兰氏阴性、不运动的需氧细菌，命名为MC 3624T。该菌在10-37 °C（最适温度25-30 °C）和pH 6.0-9.0（最适pH 8.0）条件下生长。主要脂肪酸为C16 : 0（17.7 %）、C18 : 1ω7c 11-甲基（13.4 %）、总和特征3（C16 : 1ω7c和/或C16 : 1ω6c）（10.1 %）以及总和特征8（C18 : 1ω6c和/或C18 : 1ω7c）（38.3 %）。主要呼吸醌为泛醌-10，主要极性脂为磷脂酰乙醇胺、磷脂酰甘油、双磷脂酰甘油、磷脂酰胆碱和一种未鉴定的氨基脂。DNA G+C含量为68.9 mol%。产生了螺旋藻黄素系列的类胡萝卜素。与该新菌株亲缘关系最近的是沃彭玫瑰单胞菌WW53T（16S rRNA基因序列相似性为94.36 %）。基于表型、化学分类和系统发育数据，菌株MC 3624T代表玫瑰单胞菌属的一个新物种，为此提出新名称北极玫瑰单胞菌（Roseomonas arcticisoli sp. nov.）。模式菌株为MC 3624T（=CCTCC AB 2014278T=LMG 28637T）。
