Pervasive environmental contamination due to the uncontrolled dispersal of 2,4-dinitrotoluene (2,4-DNT) represents a substantial global health risk, demanding urgent intervention for the removal of this detrimental compound from affected sites and the promotion of ecological restoration. Conventional methodologies, however, are energy-intensive, susceptible to secondary pollution, and may inadvertently increase carbon emissions. In this study, a 2,4-DNT degradation module is designed, assembled, and validated in rice plants. Consequently, the modified rice plants acquire the ability to counteract the phytotoxicity of 2,4-DNT. The most significant finding of this study is that these modified rice plants can completely degrade 2,4-DNT into innocuous substances and subsequently introduce them into the tricarboxylic acid cycle. Further, research reveals that the modified rice plants enable the rapid phytoremediation of 2,4-DNT-contaminated soil. This innovative, eco-friendly phytoremediation approach for dinitrotoluene-contaminated soil and water demonstrates significant potential across diverse regions, substantially contributing to carbon neutrality and sustainable development objectives by repurposing carbon and energy from organic contaminants.

创建环保超级“二硝基甲苯清除剂”工厂

由于 2,4-二硝基甲苯 (2,4-DNT) 不受控制的扩散造成的普遍环境污染对全球健康构成了重大风险，需要采取紧急干预措施，从受影响地点清除这种有害化合物并促进生态恢复。然而，传统的方法是能源密集型的，容易受到二次污染，并且可能无意中增加碳排放。在这项研究中，设计、组装了 2,4-DNT 降解模块，并在水稻中进行了验证。因此，修饰的水稻植物获得了抵消2,4-DNT植物毒性的能力。这项研究最重要的发现是这些转基因水稻植物可以将2,4-DNT完全降解为无毒物质，然后将其引入三羧酸循环。此外，研究表明，改良水稻植物能够快速植物修复 2,4-DNT 污染的土壤。这种针对二硝基甲苯污染的土壤和水的创新、环保的植物修复方法在不同地区表现出巨大的潜力，通过重新利用有机污染物中的碳和能量，为碳中和和可持续发展目标做出了重大贡献。
