The type strain Dietzia timorensis ID05-A0528(T), was reported to be able to survive in the highly saline and alkaline environments with diverse carbon sources. In order to more pertinently understand the genetic mechanisms of its environmental tolerance and crude oil emulsification, we reported the complete genome sequence of the strain in the study. The genome contains only one circular chromosome, with the total size of 3,607,892 bps, and the G+C content of this strain is 65.58%, much lower than other type strains of this genus. It was found that strain ID05-A0528(T) contains genes involved in transportation and biosynthesis of compatible solutes, as well as genes encoding monovalent cation/proton antiporters, which could explain its abilities to tolerate high salinity and alkalinity. Various central metabolic routes and complete alkane hydroxylation pathway were also identified in the genome of strain ID05-A0528(T), which is in accordance with its ability to use a wide spectrum of carbon sources and to degrade n-alkanes.
