外文摘要：Rapid urbanization has resulted in high diesel oil demand and consumption. Such processes are mostly carried out near coastal areas, where accidental oil spills occur during storage and handling, resulting in dieselcontaminated soils. Usually, soil microbial populations can remediate such contamination. However, the remediation of diesel-contaminated saline soils is challenging, as high salt concentrations inhibit the growth and activity of many hydrocarbon-degrading microbes, thereby limiting their remediation potential. In the current study, a combined approach was employed to remediate diesel-contaminated saline soil through bioaugmentation of a halotolerant-lipolytic fungal consortium (HLFC) and humic acid (HA) to alleviate the phytotoxicity of diesel and salt in Lolium perenne in the greenhouse experiment. The highest total petroleum hydrocarbon (TPH) degradation was achieved by the combined application of HLFC-HA (78.1 %), followed by HLFC (74.1 %), HA (65.2 %), and control (CK) (50.8 %). Plants displayed significant stress in dieselcontaminated saline soil. However, the combined application significantly reduced stress, plants showed better growth, photosynthesis, chlorophyll content, and lower antioxidant enzyme activity. Microbial diversity analysis showed that the relative abundances of the fungal genera Scopulariopsis and Aspergillus were significantly high in HLFC and HLFC-HA amended soils. Besides that, soil enzyme activity, including lipase and laccase, significantly increased in HLFC and HLFC-HA-amended soil. These findings demonstrated that HLFC-HA could be a beneficial strategy for the remediation of such oil-contaminated sites.
