摘要
石油的泄露和排放对环境造成极大的污染,迪茨氏菌(Dietzia)具有较强的石油烃降解能力,它能降解正构烷烃(C_(6)~C_(44))、姥鲛烷、植烷、多环芳烃等多种石油组分,是一种可用于石油污染生物修复技术的潜在菌种。近期关于Dietzia菌与不同物种微生物互作、菌群构建和示范应用的研究结果,为该菌的实际应用以及现场修复策略的制定提供了重要参考。对Dietzia菌的系统分类与生理特性,分离来源和分布,以及应用前景进行了总结。
Crude oil leakage and discharge have caused great environmental pollution problems.Dietzia has recently been found to possess a strong ability to degrade petroleum hydrocarbons.It can degrade multiple petroleum components such as n-alkanes(C_(6)~C_(44)),pristane,phytane,polycyclic aromatic hydrocarbons,etc.,and is a potential strain for bioremediation of crude oil pollution.Recent studies on the interaction between Dietzia and microorganisms of different species,the construction of bacterial consortium and the demonstration of application have provided important references for the practical application of Dietzia and the development of on-site bioremediation strategies.The taxonomy,physiological characteristics,isolation source,distribution,and the application prospect of Dietzia were summarized.
