从北极海水中分离到一株革兰氏反应阴性、需氧、无鞭毛、杆状、黄色素的细菌，命名为SM1502T。该菌株在10-40 °C和0-8.0NaC %(w/v)的条件下生长。基于16SRRNA基因序列的系统发育分析表明，该分离物属于黄杆菌属，与苏州黄杆菌XIN-1T的序列相似性最高(96.0 %)。菌株SM1502T的主要脂肪酸为iso-C15 ： 0、iso-C17 ： 1ω9c、iso-C15 ： 1G、C15 ： 0、iso-C17 ： 03-OH和未知ECL 13.565。SM1502T菌株的主要呼吸对苯二酚为孟喹酮-6(MK-6)。SM1502T菌株的极性脂包括磷脂酰乙醇胺和一种未知的氨基脂和脂类。SM1502T菌株基因组DNAG+C含量为37.0 摩尔%。根据本研究获得的多相数据，菌株SM1502T被认为是黄杆菌属的一个新种，命名为北极黄杆菌。11月是提议的。模式菌株为SM1502T(=KCTC 42668T=CCTCC AB 2015346T)。
A Gram-reaction-negative, aerobic, non-flagellated, rod-shaped and yellow-pigmented bacterium, designated strain SM1502T, was isolated from Arctic seawater. The isolate grew at 10–40 °C and with 0–8.0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate was affiliated with the genusFlavobacterium, with the highest sequence similarity (96.0 %) found withFlavobacterium suzhouenseXIN-1T. The major fatty acids of strain SM1502Twere iso-C15 : 0, iso-C17 : 1ω9c, iso-C15 : 1G, C15 : 0, iso-C17 : 03-OH and unknown ECL 13.565. The major respiratory quinone of strain SM1502Twas menaquinone-6 (MK-6). Polar lipids of strain SM1502Tincluded phosphatidylethanolamine and one unidentified aminolipid and lipid. The genomic DNA G+C content of strain SM1502Twas 37.0 mol%. Based on the polyphasic data obtained in this study, strain SM1502Tis considered to represent a novel species of the genusFlavobacterium, for which the nameFlavobacterium arcticumsp. nov. is proposed. The type strain is SM1502T(=KCTC 42668T=CCTCC AB 2015346T).
