| Abstract: | 2,4-and 2,6-dinitrotoluene(DNT) was focused as main target in bioremediation of explosive contaminated soil.As the basic research,a deep and systematic review was given including DNT degradation strains and their properties,bioreactors and treatment strategies,DNT degradation pathways,specific enzymes and gene clusters analysis as well as gene engineering modification.It was proposed to combine DNT degradation strains,in situ contaminated soil remediation and denitrification process together to develop an applied system of explosive-contaminated soil remediation. |

| Keywords: | DNT degradation strains treatment strategies degradation pathway gene cluster |
