A novel strain, designated 5715S-12(T), was isolated from an air sample collected from Suwon region, Republic of Korea, using R2A medium. The cells were strictly aerobic, Gram-negative, motile, short rods. Comparison of the 16S rRNA gene sequence of strain 5715S-12(T) showed the highest sequence similarities to Aurantimonas altamirensis S21B(T) (95.9 %) and Aurantimonas coralicida WP1(T) (95.4 %). Phylogenetic trees indicated that the strain formed a cluster with members of the family Aurantimonadaceae (A. altamirensis, A. coralicida and Fulvimarina pelagi). The major fatty acid was C(18 : 1) omega 7c. The predominant isoprenoid quinone was ubiquinone 10 (Q-10). Diphosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidyldimethylethanolamine, phosphatidylglycerol, phosphatidylcholine and four unknown lipids were found as the polar lipid components. The DNA G+C content was 67.0 mol%. On the basis of the phenotypic and phylogenetic features studied, we propose that strain 5715S-12(T) be assigned to a novel species of the genus Aurantimonas, for which the name Aurantimonas ureilytica sp. nov. (type strain 5715S-12(T) =KACC 11607(T) =DSM 18598(T)) is proposed.
从韩国水原地区采集的空气样本中，使用R2A培养基分离出了一株新菌株，命名为5715S-12(T)。该菌株细胞严格需氧，革兰氏阴性，具运动性，为短杆菌。菌株5715S-12(T)的16S rRNA基因序列比较显示，其与阿尔塔米拉橙单胞菌S21B(T)（95.9%）和珊瑚橙单胞菌WP1(T)（95.4%）的序列相似性最高。系统发育树表明，该菌株与橙单胞菌科的成员（阿尔塔米拉橙单胞菌、珊瑚橙单胞菌和海洋黄杆菌）形成一个簇。主要脂肪酸为C(18 : 1) ω7c。主要类异戊二烯醌为泛醌10（Q-10）。发现二磷脂酰甘油、磷脂酰单甲基乙醇胺、磷脂酰乙醇胺、磷脂酰二甲基乙醇胺、磷脂酰甘油、磷脂酰胆碱和四种未知脂质为极性脂质成分。DNA G+C含量为67.0 mol%。基于所研究的表型和系统发育特征，我们建议将菌株5715S-12(T)归入橙单胞菌属的一个新物种，为此提出新名称解脲橙单胞菌（Aurantimonas ureilytica sp. nov.）（模式菌株5715S-12(T)=KACC 11607(T)=DSM 18598(T)）。
