Embodiments of techniques for remediating soil contaminated with compounds, particularly nitro-based explosives, are disclosed. Plants capable of taking up the compounds are grown within contaminated soil for a period of time. The plants are exposed to anaerobic microbes in the rumen of a ruminant animal. The ruminal anaerobic microbes degrade the remediable compounds and render them substantially nontoxic to the animal. In some embodiments, the remediable compounds are nitroaromatic compounds, and are degraded by nitroreductases. In other embodiments, microbes are transferred from a consortium enriched in microbes capable of degrading the remediable compounds to a ruminant animal that lacks microbes capable of degrading the remediable compounds. In other embodiments, methods for isolating and identifying ruminal anaerobic microbes capable of degrading remediable compounds are disclosed.
本发明揭示了一种用于修复含有化合物的土壤,特别是含有硝基炸药的技术实施方案。在受污染的土壤中种植能够吸收这些化合物的植物,一段时间后,将这些植物暴露在反刍动物瘤胃内的厌氧微生物中。瘤胃内的厌氧微生物降解可修复的化合物,并使其在动物体内基本无毒。在某些实施方案中,可修复的化合物是硝基芳香化合物,并通过硝基还原酶降解。在其他实施方案中,从富含能够降解可修复化合物的微生物群落中转移微生物到缺乏能力降解可修复化合物的反刍动物体内。在其他实施方案中,揭示了用于分离和鉴定能够降解可修复化合物的瘤胃内厌氧微生物的方法。
