Environmental Processes Influencing the Rate of Abiotic Reduction of Nitroaromatic Compounds in the epresentatives of such nitroaromatic compounds (NACs). The high toxicity of some NACs, particularly the mutagenic and carcinogenic potential of some nitrated polycyclic aromatic hydrocarbons (PAHs), has led to considerable interest in the fate of such compounds in the environment. Due to their wides

Potential of Toluene-Degrading Systems for the Construction of Hybrid Pathways for Nitrotoluene Metacontinuous 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.

Biodegradation of 2,4,6-Trinitrotoluene by the White Rot Fungus ,le production facilities, mining sites, military firing ranges and sites where outdated explosives were burned. Continual leaching of TNT from these soils over the years has resulted in the contamination of groundwater (42, 67). Typical contaminated sites may contain average concentrations of 10,000 mg/kg TNT in soil and 100 ppm TNT in water (30).

Transformation of Inorganic N-Oxides by Denitrifying and Nitrifying Bacteriaect the existence of analogous chemistry in the reduction of NO.. or HNO. and ArNO. (where Ar is a general abbreviation for an aromatic group). Certainly both the inorganic and organic species contain nitrogen in the same oxidation state (+ 3), and they also contain two N-O bonds that possess at least partial multiple bond character.

Bacterial Degradation of Nitroaromatic Compounds under Aerobic Conditionsurther microbial attack (26). Recently, several strains of aerobic bacteria have been isolated by selection for the ability to use nitroaromatic compounds as a source of carbon or nitrogen. This chapter will focus on the metabolic strategies used by these strains for degradation of nitroaromatic compounds.

Futhermore, this new basic knowledge promises the development of field applications of biodegradation systems for nitroaromatic com- pounds. In Ma
