Research Progress About Bioremediation of Polycyclic Aromatic Hydrocarbons Contaminated Soil with Immobilized Microorganism Technique
固定化微生物技术修复PAHs污染土壤的研究进展

Polycyclic aromatic hydrocarbons (PAHs), ubiquitous in the environment, are a typical organic pollutants. Green remediation of PAHs contaminated soil has become a hot research focus. As a novel microbial remediation technique, the immobilized microorganism technology (IMT) is attracting more and more attention to restore organic contaminated soil. This paper reviewed bioremediation of polycyclic aromatic hydrocarbons contaminated soil with immobilized microorganism technique. The IMT remediation principles, selection of the immobilized carries, screening of efficient PAHs-degradation microorganism, and methods of microorganism immobilized were summarized. The research trends and currently existing problems in IMT remediation of contaminated soil were prospected.
