Abstract:
A method for reducing a concentration of a nitroaromatic compound in a fluid medium, comprising:using a fermentative microorganism to consume oxygen in the fluid medium where the fermentative microorganism is resistant to the type and concentration of the nitroaromatic compound in the fluid medium, the fluid medium comprising a carbohydrate fermentable by the fermentative microorganism; and sustaining conditions established by oxygen consumption in at least a portion of the fluid medium for a period of time sufficient for aromatic cleavage of at least a portion of the nitroaromatic compound in the fluid medium by an anaerobic micoorganism resistant to the type and concentration of the nitroaromatic compound in the fluid medium and capable of cleaving an aromatic ring of the nitroaromatic compound.
