从斯瓦尔巴群岛朗伊尔城采集的土壤样品中分离到一种革兰氏染色阴性、需氧、能动的杆状细菌，命名为6- 67 T。通过基因型、表型和化学分类学分析，研究了该菌的分类地位。该分离物在4-28 °C（最适，20 °C）、pH 5.0-9.0（最适，pH 7.0）和0- 0.2%（w/v）NaCl下生长。菌株6- 67 T含有Q-8作为主要呼吸醌，MK-7作为次要组分;主要脂肪酸为特征3（C16：1ω6c和/或C16：1ω 7 c）和C16：0。主要极性脂质为磷脂酰乙醇胺、磷脂酰甘油、二磷脂酰甘油、两种未鉴定的磷脂和一种未鉴定的氨基磷脂。多胺为腐胺和2-羟基腐胺。16 S rRNA基因序列分析表明，新菌株6- 67 T属于β-变形菌纲（Betaproteobacteria）中的草酸杆菌科（Oxalobacteraceae）。菌株6- 67 T的DNA G+C含量为56.21mol%。根据系统发育、生理学和化学分类学数据，菌株6- 67 T被认为是Undibacterium属的一个新种，并建议将其命名为Undibacterium arcticum sp. nov.。模式菌株为6- 67 T（=CCTCC AB 2015162 T =KCTC 42986 T）。
A Gram-stain-negative, aerobic, motile rod-shaped bacterium, designated 6-67T, was isolated from a soil sample collected from Longyearbyen, Svalbard. Its taxonomic position was investigated by genotypic, phenotypic and chemotaxonomic analyses. This isolate grew at 4-28 °C (optimum, 20 °C), at pH 5.0-9.0 (optimum, pH 7.0) and with 0-0.2 % (w/v) NaCl. Strain 6-67T contained Q-8 as a major respiratory quinone and MK-7 as a minor component; the major fatty acids were summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and C16 : 0. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, two unidentified phospholipids and one unidentified aminophospholipid. The polyamines were putrescine and 2-hydroxyputrescine. 16S rRNA gene sequence analysis indicated that the novel strain 6-67T belonged to the family Oxalobacteraceae within the class Betaproteobacteria. The DNA G+C content of strain 6-67T was 56.21 mol%. On the basis of phylogenetic, physiological and chemotaxonomic data, strain 6-67T is considered to represent a novel species of the genus Undibacterium, for which the name Undibacterium arcticum sp. nov. is proposed. The type strain is 6-67T (=CCTCC AB 2015162T=KCTC 42986T).
