从台湾淡水虾养殖池中分离到一株细菌，命名为CMJ-15（T），并使用多相分类方法对其进行了表征。CMJ-15（T）菌株的细胞为兼性厌氧，革兰氏染色阴性，单极鞭毛运动，形成淡黄色菌落。生长发生在20-40 °C（最佳，25-30 °C），具有0- 0.7%NaCl（最佳，0-0.2%）和pH 5.0-9.0（最佳，pH 6.0-7.0）。系统发育分析表明，CMJ-15（T）属于Undibacterium属，与Undibacterium oligocarboniphilum EM 1（T）亲缘关系最近，同源性为96.3%。主要的细胞脂肪酸是特征3（C16：1ω 7 c和/或C16：1ω6c）、C16：0和C18：1ω 7 c的总和。细胞内羟基脂肪酸主要为C10：0 3-OH。极性脂质谱由磷脂酰乙醇胺、磷脂酰甘油和二磷脂酰甘油组成。多胺谱由主要化合物腐胺和中等量的2-羟基腐胺组成。呼吸醌主要为Q-8，DNA G+C含量为52.2mol%。根据这些系统发育和表型数据，菌株CMJ-15（T）应被分类为代表一个新的物种，并建议将其命名为Undibacterium squillarum sp. nov.。模式菌株为CMJ-15（T）（= BCRC 80404（T）= LMG 26892（T）= KCTC 23917（T））。
A bacterial strain designated CMJ-15(T) was isolated from a freshwater shrimp culture pond in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain CMJ-15(T) were facultatively anaerobic, Gram-stain-negative and motile by a single polar flagellum and formed light-yellow colonies. Growth occurred at 20-40 °C (optimum, 25-30 °C), with 0-0.7% NaCl (optimum, 0-0.2%) and at pH 5.0-9.0 (optimum, pH 6.0-7.0). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain CMJ-15(T) belonged to the genus Undibacterium and its closest neighbour was Undibacterium oligocarboniphilum EM 1(T), with sequence similarity of 96.3%. The predominant cellular fatty acids were summed feature 3 (C16:1ω7c and/or C16:1ω6c), C16:0 and C18:1ω7c. The major cellular hydroxy fatty acid was C10:0 3-OH. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The polyamine profile was composed of the major compound putrescine and moderate amounts of 2-hydroxyputrescine. The major respiratory quinone was Q-8 and the DNA G+C content was 52.2 mol%. On the basis of these phylogenetic and phenotypic data, strain CMJ-15(T) should be classified as representing a novel species, for which the name Undibacterium squillarum sp. nov. is proposed. The type strain is CMJ-15(T) ( = BCRC 80404(T) = LMG 26892(T) = KCTC 23917(T)).
