Pseudomonas aeruginosa DN1 was isolated from a petroleum-contaminated soil from Changqing Oilfield with its capability to degrade high molecular weight polycyclic aromatic hydrocarbons (HMW PAHs) and crude oil. Herein, the whole genome sequence analysis of P. aeruginosa strain DN1 was reported, consisting of a size of 6,641,902 bp chromosome assembled genome (67.09 mol% G + C content) and a 317,349 bp plasmid assembled genome (57.01 mol% G + C content). According to the genome information, strain DN1 encodes various genes related to degradation of aliphatic hydrocarbons and aromatic compounds. In addition, DN1 contains gene clusters for biosynthesis and regulation of biosurfactant rhamnolipids. These genes may serve as a basis of further elucidation of the genetic background of this promising strain, and provide insights into investigating the metabolic and regulatory mechanisms of hydrocarbon biodegradation.
