Phthalic acid esters (PAEs) are a family of recalcitrant pollutants mainly used as plasticizer. The strain Gordonia sp.YC-JH1, isolated from petroleum-contaminated soil, is capable of efficiently degrading a wide range of PAEs. In order to pertinently investigate the genetic mechanism of PAEs catabolism by strain YC-JH1, its complete genome sequencing has been performed by SMRT sequencing technology. The genome comprises a circular chromosome and a plasmid with a size of 4,101,557 bp and 91,767 bp respectively. Based on the genome sequence, 3563 protein-coding genes are predicted, of which the genes responsible for PAEs degradation are identified, including the two genes of PAEs hydrolase and the gene clusters for phthalic acid and protocatechuic acid degradation. The genome information provides genomic basis of PAEs degradation to allow the complete metabolism of PAEs. The wide substrate spectrum and its genetic basis of this strain should expand its application potential for environments bioremediation, provide novel gene resources involved in PAEs degradation for biotechnology and gene engineering, and contribute to shed light on the mechanism of PAEs metabolism.
