英文摘要	Bioremediation of organic pollutants has been identified as an economically efficient and environmentally friendly method. Here, a pot experiment was conducted to evaluate the bioremediation efficiency of dibutyl phthalate (DBP) by Gordonia phthalatica sp. nov. QH-11 in agricultural soils, along with the effect of this exogenous organism on the native microbial community and ecosystem functions during the bioremediation process. The results showed that inoculation with strain QH-11 accelerated DBP degradation in the soil and decreased DBP accumulation in plants, thereby reducing the health risks associated with vegetables grown in those soils. Highthroughput sequencing demonstrated that both DBP contamination and the bioremediation process significantly altered prokaryotic community composition, structure, and network interactions; however, these effects were greatly reduced after 30 d. Dibutyl phthalate affected the prokaryotic community by influencing soil properties rather than directly impacting on microorganisms. In addition, ecosystem functions, like the nitrogen cycle, were significantly altered. Contamination with DBP promoted nitrogen fixation and the denitrification processes while inhibiting nitrification. Bioremediation may mitigate some of the changes to nitrogen cycling, helping to maintain the balance of prokaryotic community function. According to this study, bioremediation through highly efficient degradation bacteria may be a sale and promising method for reducing PAEs contamination in soilvegetable systems.
