英文摘要	Polycyclic aromatic hydrocarbons (PAHs) are one of the major pollutants in soils in oil exploring areas. Biodegradation is the major process for natural elimination of PAHs from contaminated soils. Functional genes can be used as biomarkers to assess the biodegradation potential of indigenous microbial populations. However, little is known about the distribution of PAH-degrading genes in the environment. The links between environmental parameters and the distribution of PAH metabolic genes remain essentially unclear. The present study investigated the abundance and diversity of naphthalene dioxygenase genes in the oil-contaminated soils in the Shengli Oil Field (China). Spatial variations in the density and diversity of naphthalene dioxygenase genes occurred in this area. Four different sequence genotypes were observed in the contaminated soils, with the predominance of novel PAH-degrading genes. Pearson's correlation analysis illustrated that gene abundance had positive correlations with the levels of total organic carbon and aromatic hydrocarbons, while gene diversity showed a negative correlation with the level of polar aromatics. This work could provide some new insights toward the distribution of PAH metabolic genes and PAH biodegradation potential in oil-contaminated ecosystems.; Ecology; Marine & Freshwater Biology; Microbiology; SCI(E); PubMed; 5; ARTICLE; xiesg@pku.edu.cn; yhuang@pku.edu.cn; 4; 785-793; 68
