从斯瓦尔巴群岛Kongsfjorden海域的海洋沉积物中分离到一株革兰氏阴性、橙色菌落形成、需氧、无鞭毛的细菌,命名为SM 1202(T)。16 S rRNA基因序列分析表明,菌株SM 1202(T)与偏振杆菌属(Polaribacter)有较近的亲缘关系。该菌株与Polaribacter dokdonensis的模式菌株的16 S rRNA基因序列相似性最高(94.2%),与Polaribacter属其它已知种的模式菌株的16 S rRNA基因序列相似性为92.7- 93.9%。  该菌株在4-35 °C和1.0- 5.0%(w/v)NaCl下生长。 其主要的细胞脂肪酸为iso-C15:0、iso-C15:0 3-OH、iso-C13:0、C15:0、iso-C15:1 G、iso-C17:0 3-OH和C15:1ω6c,呼吸醌主要为甲基萘醌-6(MK-6)。             菌株SM 1202(T)的极性脂为磷脂酰乙醇胺、一种未知脂、两种未知氨基磷脂和一种未知氨基脂。菌株SM 1202(T)基因组DNA G+C含量为36.4mol%。根据多相分类学研究结果,菌株SM 1202(T)代表黄杆菌科偏振杆菌属的一个新种,命名为黄河站偏振杆菌(Polaribacter huanghezhanensis sp. nov.)。模式菌株为SM 1202(T)(= CCTCC AB 2013148(T)= KCTC 32516(T))。    对该属的描述也作了修订。
A Gram-negative, orange-colony-forming, aerobic and non-flagellated bacterium, designated strain SM1202(T), was isolated from marine sediment of Kongsfjorden, Svalbard. Analysis of 16S rRNA gene sequences revealed that strain SM1202(T) was phylogenetically closely related to the genus Polaribacter. It shared the highest 16S rRNA gene sequence similarity with the type strain of Polaribacter dokdonensis (94.2 %) and 92.7-93.9 % sequence similarity with type strains of other known species of the genus Polaribacter. The strain grew at 4-35 °C and with 1.0-5.0 % (w/v) NaCl. It contained iso-C15 : 0, iso-C15 : 0 3-OH, iso-C13 : 0, C15 : 0, iso-C15 : 1 G, iso-C17 : 0 3-OH and C15 : 1ω6c as predominant cellular fatty acids and menaquinone-6 (MK-6) as the major respiratory quinone. The polar lipids of strain SM1202(T) were phosphatidylethanolamine, one unidentified lipid, two unidentified aminophospholipids and one unidentified aminolipid. The genomic DNA G+C content of strain SM1202(T) was 36.4 mol%. On the basis of the data from this polyphasic taxonomic study, strain SM1202(T) represents a novel species in the genus Polaribacter of the family Flavobacteriaceae, for which the name Polaribacter huanghezhanensis sp. nov. is proposed. The type strain of Polaribacter huanghezhanensis is SM1202(T) ( = CCTCC AB 2013148(T) = KCTC 32516(T)). An emended description of the genus Polaribacter is also presented.
