从斯瓦尔巴群岛Kongsfjorden表层海水中分离到一株革兰氏阴性、黄色素、需氧、无鞭毛、不滑行的细菌，命名为SM1203T。基于16S rRNA基因序列的系统发育分析表明，菌株SM1203T属于黄杆菌科黄杆菌属。该菌株的16S rRNA基因序列相似性最高(96 %)，与海绵福尔摩沙(96.8 %)、副双歧杆菌(96.3 %)、沙棘双歧杆菌(96.3 %)和B。Echini(96.1 %)和95.4-95.7 %的序列与该属其他已知种的模式菌株序列相似。该菌株在4-30 °C和1.0-5.0 %(w/v)氯化钠存在下生长。菌株SM1203T的主要脂肪酸为iso-C15 ： 0、iso-C15 ： 1、Anteo-C15 ： 0和C15 ： 0，主要极性脂为磷脂酰乙醇胺和一种未知脂。SM1203T菌株的主要呼吸对苯二酚为孟喹酮6(MK-6)。SM1203T菌株基因组DNAG+C含量为34.8 摩尔%。根据菌株SM1203的多相特性，本研究中该菌株代表了Bizionia属的一个新种，命名为Bizionia arcticasp。11月是提议的。模式菌株为SM1203T( = CGMCC1.12751T= JCM30333T)。文中还对该属进行了订正描述。
A Gram-stain-negative, yellow-pigmented, aerobic, non-flagellated, non-gliding bacterial strain, designated SM1203T, was isolated from surface seawater of Kongsfjorden, Svalbard. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SM1203Twas affiliated with the genusBizioniain the familyFlavobacteriaceae. The strain shared the highest 16S rRNA gene sequence similarity (>96 %) with the type strains ofFormosa spongicola(96.8 %),Bizionia paragorgiae(96.3 %),B. saleffrena(96.3 %) andB. echini(96.1 %) and 95.4–95.7 % sequence similarity with the type strains of other known species of the genusBizionia. The strain grew at 4–30 °C and in the presence of 1.0–5.0 % (w/v) NaCl. The major fatty acids of strain SM1203Twere iso-C15 : 0, iso-C15 : 1, anteiso-C15 : 0and C15 : 0and the main polar lipids were phosphatidylethanolamine and an unidentified lipid. The major respiratory quinone of strain SM1203Twas menaquinone 6 (MK-6). The genomic DNA G+C content of strain SM1203Twas 34.8 mol%. Based on the polyphasic characterization of strain SM1203Tin this study, the strain represents a novel species in the genusBizionia, for which the nameBizionia arcticasp. nov. is proposed. The type strain is SM1203T( = CGMCC 1.12751T= JCM 30333T). An emended description of the genusBizioniais also given.
