摘要: 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.
