从冰碛物样品中分离到一株淡黄色需氧细菌，菌株M0-2（T）。用多相分类法对其分类地位进行了研究。细胞呈革兰氏染色阴性，杆状，有运动能力。通过出芽或不对称细胞分裂繁殖的细胞。基于16 S rRNA基因序列的系统发育分析表明，菌株M0-2（T）属于鞘氨醇单胞菌科，与新鞘氨醇菌属的物种关系密切（96.4-92.0%）和芽生单胞菌（94.6%）、卫氏鞘氨醇单胞菌W-50（T）（94.0%）、土壤鞘氨醇单胞菌KSL-125（T）（93.6%）和炭疽鞘氨醇单胞菌TDMA-17（T）（93.5%）。泛醌-10（Q-10）是主要的呼吸醌。主要脂肪酸为合计特征8（包含C18：1ω 7 c和/或C18：1ω6c，31.9%）、合计特征3（包含C16：1ω 7 c和/或C16：1ω6c，19.8%）和C14：0 2-OH（8.9%）。主要极性脂质为鞘糖脂、磷脂酰乙醇胺、二磷脂酰甘油、磷脂酰甘油和磷脂酰胆碱。亚精胺是细胞中观察到的主要多胺。基因组DNA G+C含量为47.5mol%。基于系统发育关系和与鞘氨醇单胞菌科大多数其他属相比低的DNA G+C含量，结合表型和化学分类学数据，菌株M0-2（T）被认为是鞘氨醇单胞菌科中一个新属中的一个新种，sp. nov.的报道。北极副芽单胞菌gen. nov.的模式菌株，nov.为M0-2（T）（=CCTCC AB 2012968（T）= NRRL B-59110（T））。
A pale yellow, aerobic bacterium, strain M0-2(T), was isolated from a till sample. Its taxonomic position was investigated by using a polyphasic approach. Cells were Gram-stain-negative, rod-shaped and motile. Cells reproduced by budding or asymmetrical cell division. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain M0-2(T) belonged to the family Sphingomonadaceae and was closely related to species of the genera Novosphingobium (96.4-92.0%) and Blastomonas (94.6%), Sphingopyxis witflariensis W-50(T) (94.0%), Sphingosinicella soli KSL-125(T) (93.6%) and Sphingomonas astaxanthinifaciens TDMA-17(T) (93.5%). Ubiquinone-10 (Q-10) was the predominant respiratory quinone. The major fatty acids were summed feature 8 (comprising C18:1ω7c and/or C18:1ω6c, 31.9%), summed feature 3 (comprising C16:1ω7c and/or C16:1ω6c, 19.8%) and C14:0 2-OH (8.9%). Sphingoglycolipid, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine were the major polar lipids. Spermidine was the major polyamine observed in the cell. The genomic DNA G+C content was 47.5 mol%. On the basis of phylogenetic relationships and the low DNA G+C content compared with most other genera of the family Sphingomonadaceae, combined with phenotypic and chemotaxonomic data, strain M0-2(T) is considered to represent a novel species in a new genus in the family Sphingomonadaceae for which the name Parablastomonas arctica gen. nov., sp. nov. is proposed. The type strain of Parablastomonas arctica gen. nov., sp. nov. is M0-2(T) ( =CCTCC AB 2012968(T) = NRRL B-59110(T)).
