纳米材料对土壤微生物影响及其对土壤有机污染物的降解机制和应用

不同纳米材料如铁矿物和黏土矿物纳米颗粒对微生物降解有机污染物的影响及其分子机制，为开发纳米生物修复技术奠定了理论基础；制备了固定化微生物菌剂，探明了固定化菌剂对多环芳烃污染土壤的强化修复效应及机制，建立了多环芳烃污染土壤纳米材料强化根际修复技术和固定化微生物强化修复技术

The impacts of various nanomaterials (e.g., iron minerals and clay mineral nanoparticles) on microbial degradation of organic pollutants and their underlying molecular mechanisms laid a theoretical foundation for the development of nanobioremediation technologies. Immobilized microbial inoculants were prepared, the enhanced remediation effects and mechanisms of the immobilized inoculants on polycyclic aromatic hydrocarbon (PAH)-contaminated soil were elucidated, and nanomaterial-enhanced rhizoremediation technology and immobilized microorganism-enhanced remediation technology for PAH-contaminated soil were established.
