植物-微生物联合修复石油烃污染土壤研究进展

A Review on the Progress of Plant-microbiota Combination in Repairing Petroleum Hydrocarbon Contaminated Soil

石油烃污染引发了严重的土壤污染问题,在各种修复技术当中,植物-微生物联合修复技术以成本低、修复效果好、二次污染少等优点得到广泛重视。文章以植物-微生物联合修复技术为中心,阐述了内生菌-植物联合修复和植物-根际微生物联合修复两种典型的联合修复技术的原理以及最新的应用进展,并总结了当前植物-微生物联合修复技术研究的不足,以期为石油烃污染土壤的生物修复提供参考。

Petroleum hydrocarbon contamination has led to severe soil pollution issues.Among various remediation techniques,the plant-microbe combined remediation technology has garnered widespread attention due to its advantages such as low cost,effective remediation,and minimal secondary pollution.Centered on the plant-microbe combined remediation technology,this article elaborates on the principles and recent advancements in two typical combined remediation techniques:endophytic bacteria-plant combined remediation and plant-rhizosphere microbe combined remediation.Furthermore,it summarizes the current deficiencies in research on plant-microbe combined remediation technology,aiming to provide a reference for the bioremediation of petroleum hydrocarbon-contaminated soil.
