Tistrella mobilis gen. nov., sp. nov., a novel polyhydroxyalkanoate-producing bacterium belonging to α-Proteobacteria

Abstract

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 C18:1ω7c, 2-OH C18:0 and 3-OH C14:0. 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 14872T (=TISTR 1108T).
