A marine bacterial strain, designated A71(T), was isolated from marine algae collected from the South Sea, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain A71(T) belonged to the family Flavobacteriaceae and was closely related to Aequorivita antarctica SW49(T) (96.5 % sequence similarity). Cells of strain A71(T) were Gram-negative, aerobic, oxidase-negative, catalase-positive, yellow/orange-pigmented and non-motile. The major fatty acids were iso-C(15 : 0) (20.6 %), iso-C(17 : 1)omega9c (13.3 %), anteiso-C(15 : 0) (13.1 %), iso-C(17 : 0) 3-OH (12.7 %) and summed feature 3 (comprising iso-C(15 : 0) 2-OH and/or C(16 : 1)omega7c; 6.6 %). The DNA G+C content was 36.9 mol%. Several phenotypic characteristics served to differentiate the isolate from recognized members of the genus Aequorivita. Data from this polyphasic study clearly demonstrated that strain A71(T) represents a novel species of the genus Aequorivita. The name Aequorivita capsosiphonis sp. nov. is proposed, with strain A71(T) (=KCTC 22183(T) =JCM 15070(T)) as the type strain. In addition, an emended description of the genus Aequorivita is presented.
从韩国南海采集的海藻中分离出一株海洋细菌，命名为A71(T)。基于16S rRNA基因序列的系统发育分析表明，菌株A71(T)属于黄杆菌科，与南极水色菌SW49(T)密切相关（序列相似性为96.5%）。菌株A71(T)的细胞革兰氏阴性、需氧、氧化酶阴性、过氧化氢酶阳性、黄色/橙色色素沉着且不运动。主要脂肪酸为异-C(15 : 0)（20.6%）、异-C(17 : 1)ω9c（13.3%）、anteiso-C(15 : 0)（13.1%）、异-C(17 : 0) 3-OH（12.7%）和总和特征3（包括异-C(15 : 0) 2-OH和/或C(16 : 1)ω7c；6.6%）。DNA G+C含量为36.9 mol%。几个表型特征有助于将该分离株与水色菌属的已知成员区分开来。这项多相研究的数据清楚地表明，菌株A71(T)代表水色菌属的一个新物种。提出新物种名称水色菌紫菜种（Aequorivita capsosiphonis sp. nov.），菌株A71(T)（=KCTC 22183(T) =JCM 15070(T)）为模式菌株。此外，还给出了水色菌属的修订描述。
