从日本江之岛（神奈川藤泽）附近的太平洋海岸线采集的海水样品中分离到一种新的海洋细菌（菌株TD-ZE 3（T）），该细菌为革兰氏阴性、黄色、杆状、严格需氧、滑动且氧化酶和过氧化氢酶阳性。基于16 S rRNA基因序列的系统发育分析表明，菌株TD-ZE 3（T）属于黄杆菌科（Flavobacteriaceae）中的一个独特的分支，与最近的物种Robiginitalabiformata的序列相似性为90.5%。菌株TD-ZE 3（T）在化学分类学和表型特征上与黄杆菌科其他成员相区别。DNA G + C含量为46.5mol%。主要的脂肪酸是iso-C-15：0、iso-C-17：0 3-OH和iso-C-17：1 omega 9 c，甲基萘醌-6是唯一的呼吸醌。玉米黄质是产生的主要类胡萝卜素色素;没有产生flexirubin型色素。菌株TD-ZE 3（T）降解明胶、淀粉和吐温80。基于其独特的表型、基因型和系统发育特征，菌株TD-ZE 3（T）代表了一个新的分类单元，其名称为泽黄杆菌（Zeaxanthinibacter enoshimensis gen. nov.），sp. nov.的报道。模式菌株为TD-ZE 3（T）（=NBRC 101990（T）-CCUG 53613（T））。
A novel marine, Gram-negative, yellow-pigmented, rod-shaped, strictly aerobic, gliding and oxidase- and catalase- positive bacterium (strain TD-ZE3(T)) was isolated from a seawater sample collected off the Pacific coastline of Japan near Enoshima Island (Fujisawa, Kanagawa). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain TD-ZE3(T) belonged to a distinct lineage in the family Flavobacteriaceae, with 90.5 % sequence similarity with the nearest species Robiginitalea biformata. Strain TD-ZE3(T) could be distinguished from other members of the family Flavobacteriaceae by a number of chemotaxonomic and phenotypic characteristics. The DNA G + C content was 46.5 mol%. The major fatty acids were iso-C-15:0, iso-C-17:0 3-OH and iso-C-17:1 omega 9c and menaquinone-6 was the only respiratory quinone. Zeaxanthin was the major carotenoid pigment produced; flexirubin-type pigments were not produced. Strain TD-ZE3(T) degraded gelatin, starch and Tween 80. Based on its unique phenotypic, genotypic and phylogenetic features, strain TD-ZE3(T) represents a novel taxon, for which the name Zeaxanthinibacter enoshimensis gen. nov., sp. nov. is proposed. The type strain is TD-ZE3(T) (=NBRC 101990(T) -CCUG 53613(T)).
