从中国南极长城站附近的南极海水中分离到一株革兰氏染色阴性、需氧、无鞭毛的杆状细菌，命名为SM 1703 T。基于16 S rRNA基因序列的系统发育分析表明，菌株SM 1703 T与Marivita litorea的16 S rRNA基因序列相似性高达95.5%，属于杜鹃花科（Rhododocellaceae）的一个分支。该菌株在10-37 °C（最佳，25 °C）和0.5-13%（w/v）NaCl（最佳，3-5%）下生长。主要的细胞脂肪酸为C19：0环ω 8 c、C18：1ω 7 c、C18：12-OH和C16：02-OH。主要极性脂质为磷脂酰甘油、磷脂酰胆碱、一种未鉴别的氨基脂质和一种未鉴别的脂质。菌株SM 1703 T基因组DNA G+C含量为64.6mol%。根据菌株SM 1703 T的多相性特征，将其分类为杜鹃花科一新属的代表种，命名为Chachezhania anaparticagen。十一月，sp. nov.的报道。模式菌株为SM 1703 T（= MCCC 1 K 03470 T = KCTC 62794 T = CCTCC AB 2018351 T）。
A Gram-stain-negative, aerobic, non-flagellated, rod-shaped bacterium, designated strain SM1703T, was isolated from Antarctic seawater collected near the Chinese Antarctic Great Wall Station, King George Island, West Antarctica. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SM1703Tformed a distinct phylogenetic lineage within the family ‘Rhodobacteraceae’, sharing high 16S rRNA gene sequence similarity withMarivita litorea(95.5%). The strain grew at 10–37 °C (optimum, 25 °C) and with 0.5–13% (w/v) NaCl (optimum, 3–5%). The major cellular fatty acids were C19:0cycloω8c, C18:1ω7c, C18:12-OH and C16:02-OH. The major polar lipids were phosphatidylglycerol, phosphatidylcholine, an unidentified aminolipid and an unidentified lipid. The genomic DNA G+C content of strain SM1703Twas 64.6 mol%. Based on the results of the polyphasic characterization for strain SM1703T, it is classified as the representative of a novel species in a new genus of the family ‘Rhodobacteraceae’, for which the nameChachezhania antarcticagen. nov., sp. nov. is proposed. The type strain ofChachezhania antarcticais SM1703T(= MCCC 1K03470T= KCTC 62794T= CCTCC AB 2018351T).
