Strain IAM 14872, isolated from wastewater in Thailand, is capable of producing polyhydroxyalkanoate. This bacterium is Gram-negative, rod-shaped, strictly aerobic and highly motile with a single polar flagellum. Both oxidase and catalase activities are positive. The G+C content of DNA is 67.5% and Q-10 is the major quinone. The major cellular fatty acids are C(18:1)omega7c, 2-OH C(18:0) and 3-OH C(14:0). On the basis of the 16S rDNA sequence analysis and phenotypic properties, it is proposed that the strain IAM 14872 be classified in a new genus as Tistrella mobilis gen. nov., sp. nov. The type strain is IAM 14872(T) (=TISTR 1108(T)).
从泰国废水中分离出的菌株IAM 14872能够产生聚羟基脂肪酸酯。该细菌为革兰氏阴性、杆状，严格需氧，具有单根极生鞭毛，运动性很强。氧化酶和过氧化氢酶活性均为阳性。DNA的G+C含量为67.5%，主要醌类为Q-10。主要细胞脂肪酸为C(18:1)ω7c、2-OH C(18:0)和3-OH C(14:0)。基于16S rDNA序列分析和表型特征，建议将菌株IAM 14872归入一个新属，命名为运动蒂斯特氏菌（Tistrella mobilis），新属，新种。模式菌株为IAM 14872(T)（=TISTR 1108(T)）。
