背景:石油是作为燃料的主要能源。石油泄漏或倾倒石油废料会污染土壤和地下水。石油泄漏的一些主要来源是储油罐泄漏、管道泄漏、石油废物的陆地处理和意外泄漏。植物修复是利用植物及其相关微生物。目的:利用莎草、C. odoratus和PGPR菌株对油泥污染土壤进行植物修复。材料和方法:植物在两种条件下生长，即石油污染的土壤和含有PGPR的污染土壤。观察了两种条件下植物的生长规律。采用索氏提取法估算石油总烃类(TPH)。GC-MS对TPH样品进行进一步分析。结果:种植1个月后，在污染土壤中施用PGPR处理后，能较好地生长。 Initially when treated with the plant there was no change in the amount of total petroleum hydrocarbon but after treating with PGPR strains there was a decrease in the concentration of total petroleum hydrocarbon. Moreover, GCMS reveals that there is a breakdown of hydrocarbon when the soil are planted with C. odoratus and treated with Plant Growth Promoting Rhizobia (PGPR). Conclusion: A synergistic effect of Cyperus odoratus & PGPR strain in hydrocarbon uptake was observed. So, this combination could be effectively used to restore vegetation in oil spilled sites.
