A novel Gram-stain-negative, aerobic, rod-shaped, non-flagellated and non-gliding bacterium, designated FA042T, was isolated from a marine sediment sample collected from the coast of Weihai, China (37° 32' 02″ N 122° 03' 44″ E). Optimal growth occurred at 33 °C, pH 7.0-7.5 and in the presence of 2-3 % (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain FA042T belonged to the genus Hyunsoonleella. The closest described neighbour, in terms of 16S rRNA gene sequence identity, was Hyunsoonleella jejuensis (95.0 %). The major fatty acids were iso-C15 : 0, iso-C15 : 1 G, C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 0 3-OH. The major respiratory quinone was MK-6. The major polar lipids of strain FA042T were phosphatidylethanolamine, three unidentified lipids and two unidentified aminolipids. The DNA G+C content was 38.5 mol%. Based on its phylogenetic and phenotypic characteristics, strain FA042T is presented as a representative of a novel species, for which the name Hyunsoonleella rubra sp. nov. is proposed. The type strain of Hyunsoonleella rubra sp. nov. is FA042T (=KCTC 42398T=MCCC 1H00110T).
从中国威海海岸（北纬37° 32' 02″，东经122° 03' 44″）采集的海洋沉积物样本中分离出一株新型革兰氏阴性、需氧、杆状、无鞭毛且不滑动的细菌，命名为FA042T。该菌在33 °C、pH 7.0 - 7.5以及2 - 3 %（w/v）NaCl存在的条件下生长最佳。基于16S rRNA基因序列的系统发育分析表明，菌株FA042T属于Hyunsoonleella属。就16S rRNA基因序列同一性而言，与其最接近的已描述邻种是济州Hyunsoonleella jejuensis（95.0 %）。主要脂肪酸为异-C15 : 0、异-C15 : 1 G、C15 : 0、异-C17 : 0 3-OH和异-C15 : 0 3-OH。主要呼吸醌为MK-6。菌株FA042T的主要极性脂为磷脂酰乙醇胺、三种未鉴定的脂类和两种未鉴定的氨基脂类。DNA G+C含量为38.5 mol%。基于其系统发育和表型特征，菌株FA042T被视为一个新物种的代表，为此提出新名称红色Hyunsoonleella rubra sp. nov.。红色Hyunsoonleella rubra sp. nov.的模式菌株为FA042T（=KCTC 42398T=MCCC 1H00110T）。
