摘要
丛枝菌根(Arbuscular mycorrhiza,AM)是由丛枝菌根真菌与植物根系所建立的一种互惠共生体,在自然界分布广泛,具有降解复杂有机污染物的能力。石油污染土壤中,利用土著的或外接的丛枝菌根真菌可以明显改善植物根际环境,提高土壤生物活性,从而加速土壤中石油污染物的降解。现有研究已证明丛枝菌根真菌修复石油污染土壤的可行性,并就丛枝菌根真菌与土壤其它微生物及植物联合修复效果等进行了多方面的有益探索,然而这一技术的研发与实际应用尚有很大距离。文章重点综述了国内外丛枝菌根真菌-植物联合修复石油污染土壤的研究现状,并探讨了这一生物修复技术在石油污染土壤治理中存在的限制因素、发展趋势和应用前景,旨在促进菌根生物技术在石油污染土壤修复中的应用与发展。
Arbuscular mycorrhiza（AM） are ubiquitous symbiotic associations between plants and microbes found in natural ecosystems.AM fungi are essential components of sustainable soil-plant systems.Indigenous and exogenous AM fungi infection can increase the bioremediation efficiency of petroleum-contaminated soil by improving soil microenvironment in the rhizosphere of host plant and by influencing microbial activities.Existing researches showed that AM bioremediation is an available and effective technology.Effects of AM fungi and plant bioremediation were discussed,as well as analysis of the limitations and distance between the research development and practical application.Progress and achievement of AM bio-technology were introduced including its main shortcomings and application prospect of AM bioremediation to petroleum-contaminated soil,which aimed at facilitating the practical application of AM biotechnology in oil contaminated soil.
