A novel, red-pink-pigmented strain, designated R2-4(T), was isolated from a till sample near Ny-Alesund, Svalbard Archipelago, Norway. Cells were aerobic, Gram-stain-negative and rod-shaped. Growth occurred at 4-30 °C (optimum, 20-22 °C), at pH 6.0-9.0 (optimum, pH 7.0) and with 0-1% NaCl added to R2A agar. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain R2-4(T) belonged to the genus Hymenobacter. 16S rRNA gene sequence similarity between strain R2-4(T) and the type strains of related species of the genus ranged from 94.51 to 96.05%. Strain R2-4(T) contained iso-C(15 : 0), anteiso-C(15 : 0), summed feature 3 (C(16 : 1)ω6c and/or C(16 : 1)ω7c), summed feature 4 (C(17 : 1) anteiso B and/or iso I) and C(16 : 1)ω5c as the major cellular fatty acids, MK-7 as the major respiratory quinone, and phosphatidylethanolamine, unknown aminophospholipids, unknown aminolipids and unknown lipids as the main polar lipids. The polyamine was sym-homospermidine. The DNA G+C content of strain R2-4(T) was 61.6 mol%. On the basis of phylogenetic, physiological and chemotaxonomic data, strain R2-4(T) is considered to represent a novel species of the genus Hymenobacter, for which the name Hymenobacter arcticus sp. nov. is proposed. The type strain is R2-4(T) ( = CCTCC AB 2012104(T) = KACC 16881(T)).
一株新型的、呈红粉色的菌株，被命名为 R2-4(T)，是从挪威斯瓦尔巴群岛的新奥尔松附近的一个耕作样本中分离出来的。细胞是需氧的、革兰氏阴性的和杆状的。在 R2A 琼脂上生长，温度范围为 4-30°C（最佳温度为 20-22°C），pH 值范围为 6.0-9.0（最佳 pH 值为 7.0），添加 0-1%的 NaCl。基于 16S rRNA 基因序列的系统发育分析表明，菌株 R2-4(T)属于海氏杆菌属。菌株 R2-4(T)与相关种属的模式菌株的 16S rRNA 基因序列相似度为 94.51%至 96.05%。菌株 R2-4(T)含有异-C(15：0)、anteiso-C(15：0)、特征 3( C(16：1)ω6c 和/或 C(16：1)ω7c)、特征 4(C(17：1)anteiso B 和/或 iso I)和 C(16：1)ω5c 作为主要的细胞脂肪酸，MK-7 作为主要的呼吸醌，磷脂酰乙醇胺、未知的氨基磷脂、未知的氨基脂和未知的脂类作为主要的极性脂类。多胺是 sym-homospermidine。菌株 R2-4(T)的 DNA G+C 含量为 61.6 mol%。基于系统发育、生理和化学分类学数据，菌株 R2-4(T)被认为代表了海氏杆菌属的一个新型物种，建议将其命名为北极海氏杆菌新种。模式菌株为 R2-4(T)(= CCTCC AB 2012104(T)=KACC 16881(T))。
