摘要
从化学转化及微生物降解2个方面综述了2,4,6‑三硝基甲苯(TNT)资源化再利用的研究进展及应用。化学转化途径以TNT甲基氧化、硝基还原、取代反应等进行分类,系统地梳理了多样性的化学转化途径,结合资源化再利用从绿色环保、反应机理、反应效率、产物特性等多个维度进行了评价;微生物转化途径以需氧细菌、厌氧细菌和真菌代谢进行分类,较为全面的梳理了TNT微生物需氧代谢和厌氧代谢途径,汇总了相关微生物及代谢过程。最后对基于化学转化和生物转化的废旧TNT资源化再利用发展方向进行了展望:TNT化学转化将超越实验室研究阶段,绿色工艺研究及安全性将是本阶段研究的重点;TNT微生物转化依旧是研究重点,结合基因工程及现代分子生物学技术,有望为废旧TNT深度再利用提供新的解决方案。
This review summarized progress of 2,4,6‑trinitrotoluene(TNT)multifarious reutilization in the aspects of chemical transformation and microorganism degradation.Chemical transformation pathways are classified into TNT methyl oxidation,nitro reduction,and substitution reaction.The diverse chemical transformation pathways were systematically summarized according to the green environmental protection,reaction mechanism,reaction efficiency and product properties combined with resource reuse.The microorganism transformation pathways are classified into aerobic bacteria,anaerobic bacteria and fungus.A more comprehensive overview of the aerobic and anaerobic metabolic pathways of TNT microorganisms is presented,summarizing the relevant microorganisms.Finally,the development direction of waste TNT resourceful reuse based on chemical and biological transformation is prospected.Chemical transformation of TNT will go beyond the laboratory research stage,and green process research and safety will be the focus of this stage of research.Microbial transformation of TNT remains the focus of research,and combined with genetic engineering and modern molecular biology technology,it is expected to provide new solutions for deep reuse of waste TNT.
