SUMMARY Nitroaromatic compounds are relatively rare in nature and have been introduced into the environment mainly by human activities. This important class of industrial chemicals is widely used in the synthesis of many diverse products, including dyes, polymers, pesticides, and explosives. Unfortunately, their extensive use has led to environmental contamination of soil and groundwater. The nitro group, which provides chemical and functional diversity in these molecules, also contributes to the recalcitrance of these compounds to biodegradation. The electron-withdrawing nature of the nitro group, in concert with the stability of the benzene ring, makes nitroaromatic compounds resistant to oxidative degradation. Recalcitrance is further compounded by their acute toxicity, mutagenicity, and easy reduction into carcinogenic aromatic amines. Nitroaromatic compounds are hazardous to human health and are registered on the U.S. Environmental Protection Agency's list of priority pollutants for environmental remediation. Although the majority of these compounds are synthetic in nature, microorganisms in contaminated environments have rapidly adapted to their presence by evolving new biodegradation pathways that take advantage of them as sources of carbon, nitrogen, and energy. This review provides an overview of the synthesis of both man-made and biogenic nitroaromatic compounds, the bacteria that have been identified to grow on and completely mineralize nitroaromatic compounds, and the pathways that are present in these strains. The possible evolutionary origins of the newly evolved pathways are also discussed.

“…The activated sludge used in this work was collected from a wastewater treatment plant (located in Xi'an, Shaanxi Province, China) that treated wastewater contaminated with 2-PA. A certain volume (10 mL) of the activated sludge was aseptically added to 90 mL of the sterilized MS medium (pH=7.0) [9] in a 250 mL flask. The 250 mL flask was supplemented with 2-PA with a concentration of 100 mg/L and placed in a rotary shaker (ZHWY-2102C, Zhicheng Analytical Instrument Manufacturing Co., Ltd., Shanghai, China) at 180 r/ min and 30°C.…”

“…isolated by Cai et al [9] could degrade 93.5% of nitrobenzene within 24 h. Li et al [10] isolated a strain Pseudomonas putida which was able to degrade nitrobenzene at low temperature. Micrococcus luteus [11] and Rhodotorula mucilaginosa [12] were reported for degrading nitrobenzene in high salinity. However, the metabolic activity and cell growth of most of the microorganisms reported are weak at a high nitrobenzene concentration.…”

An efficient nitrobenzene degrading bacterium strain NB5, which was able to utilize nitrobenzene as a sole source of carbon, nitrogen and energy under aerobic condition, was isolated from activated sludge in an oil refinery at Hangzhou, China. Based on phenotypic features, 16S rDNA gene sequencing and G + C content analysis, strain NB5 was identified as Rhodococcus sp. NB5. Nitrobenzene degradation experiments using high performance liquid chromatograph (HPLC) showed that strain NB5 could tolerate a high nitrobenzene concentration and completely degrade nitrobenzene with initial concentration ranging from 100 mg · l(-1) to 1000 mg · l(-1) within 144 h. The optimal degradation and cell growth were observed at 30 °C, pH 7.0. The addition of second nitrogen source (0.1%) such as urea, peptone, yeast extract and beef extract generally enhanced degradation of nitrobenzene. Rhodococcus sp. strain NB5 could be an excellent candidate for biotreatment of industrial wastewater containing high concentration of nitrobenzene.
