摘要
石油污染土壤的生物修复以其成本低、环境友好而具有良好的发展前景。生物修复的研究主要集中在难降解的重质石油烃尤其是芳烃的生物降解基因和机理的研究。微观上应用分子生物学技术探索石油烃生物降解的机理、宏观上应用先进的仪器研究石油烃的降解和物理参数相关性的规律,筛选优势降解菌或菌群培育高效基因工程菌,通过对降解石油中重质组分的菌群进行群落分析和同生菌群的强化研究,认为不可培养微生物的研究和从分子水平重建石油降解微生物区系是一个重要的研究方向。
Bioremediation of petroleum-polluted soil which is cost-effective, good safety and friendly to environment is promising. This paper focuses on the followings: the bioremediation of heavy oil which is difficult to be biodegraded; exploitation the mechanism of bioremediation of polluted soil with molecular biotechnology;study of the principles between the biodegradation of heavy oil and the physical parameters. The excellent strains or bacterium community are screened and gene engineering bacteria are constructed. The application of bioremediation in engineering-scale is a trend. The application of molecular biotechnology make it possible that the study of the uncultured microbes, so that it enhances corporation with indigenous microflora.
