Bioremediation has become one of the most rapidly developing fields for reducing concentration and toxicity of the pollutants. Current studies focuses on the harmful effects of p-nitrophenol, microbial features in biodegradation, biological solution to the pollution and effect of various physico-chemical factors on biodegradation. Information collected from different reviews is duly incorporated in the chapter. Decontamination of nitro-aromatic compounds to less harmful or nontoxic products is achieved with various methods like land farming, bioventig, bioaugmentation, biostimulation etc. The world-wide annual production of nitro-aromatics is about 108 tons, while p-nitrophenol alone contributes 20 million kg per annum. Microorganisms like fungi, bacteria are playing an important role in transforming para-nitrophenols and in the associated recycling of the nitrogen. Potential of biological solutions for remediation of nitro-aromatics has been reviewed by considering the central role of microbes in nutrient cycling through their vast enzymatic capacity to transform anthropogenic waste from diverse sources into non-toxic products. In this chapter, effects of various physicochemical parameters on microbial degradation of p-nitrophenol are reviewed.
