Abstract

Environmental pollutants like polyaromatic hydrocarbons (PAHs) due to their persistence, carcinogenicity, and toxicity have created havoc. Benzopyrene, naphthalene, anthracene, and phenanthrene are main aromatic hydrocarbons which are ubiquitous and recalcitrant causing majority of the problems associated with PAHs. Bioremediation using various microorganisms or active consortia can effectively degrade these hydrocarbons. This chapter enlists the properties and the hazards associated with these PAHs. The overall procedure of bioremediation including the factors affecting is also discussed charting the main bacterial and fungal species involved in biodegradation of these hydrocarbons. Through the works of many researchers, many new species or an actively respiring consortium of species, namely, Mycobacterium, Sphingobacterium, Sphingomonas, Pseudomonas, Alteromonas, Streptomyces, and fungi like Irpex lacteus and Aspergillus fumigatus, have emerged as potential PAH degraders. The biochemical basis as well as the impact, various techniques used, and efficiency of these species for each of the above four hydrocarbons in contaminated soil samples, tidal sample, petrochemical refinery, and mangrove soils has been individually discussed.
