A 150-day experiment was performed to investigate the stimulatory effect of a promising phytoremediation strategy consisting of (), (), and oil-degrading bacteria for cleaning up total petroleum hydrocarbons (TPHs) in spiked sediment. Inoculation with oil-degrading bacteria and/or increased plant yield and TPH accumulation in plants. The highest TPH dissipation (40.5%) was obtained in the combination treatment, i.e., + oil-degrading bacteria + , in which the sediment TPH concentration decreased from an initial value of 3955 to 2355 mg/kg in 150 days. BAF, BCF, and TF confirmed the role of and oil-degrading bacteria in the amelioration and translocation of TPHs. In addition, TPH toxicity of was alleviated by and oil-degrading bacteria addition through the reduction of oxidative stress. Therefore, could be used for cleaning up oil-contaminated sediment, particularly in the presence of oil-degrading bacteria + . Field studies on oil-degrading bacteria + may provide new insights on the rehabilitation and restoration of sediments contaminated by TPHs.
进行了一项为期 150 天的实验，以研究一种有前途的植物修复策略的刺激效果，该策略由（）、（）和石油降解菌组成，用于清理污染沉积物中的总石油烃（TPH）。接种石油降解菌和/或（）增加了植物的产量和（）植物中 TPH 的积累。在组合处理中，即（）+石油降解菌+（），获得了最高的 TPH 消散（40.5%），其中沉积物 TPH 浓度在 150 天内从初始值 3955 降至 2355mg/kg。BAF、BCF 和 TF 证实了（）和石油降解菌在 TPH 改良和转移中的作用。此外，通过减少氧化应激，添加（）和石油降解菌缓解了 TPH 对（）的毒性。因此，（）可用于清理受油污染的沉积物，特别是在存在石油降解菌+（）的情况下。关于石油降解菌+（）的现场研究可能为 TPH 污染沉积物的修复和恢复提供新的见解。
