Wastes from manufacturing processes, together with the widespread use of some nitroaromatic compounds, have polluted waters and soils. Because of their toxicity and mutagenicity, some of these compounds have been designated pollutants whose elimination is a high priority (25). A variety of alternative treatments including physical, chemical and biological (21), have been developed to reduce or eliminate contamination due to hazardous nitroorganic compounds. Physical treatments comprise absorption to activated carbon, filtration and incineration. Chemical approaches involve solvent extraction or surfactant precipitation. These treatments are expensive, and may in some cases generate unwanted products (22). The biological approach, including continuous and batch treatments of liquid wastes, and composting and soil treatments, is usually cheaper and involves less risk to human health or the environment (12, 23, 54). However, nitroaromatic compounds are relatively refractory to mineralization by microbes.
