Polycyclic Aromatic Hydrocarbons and Their Importance in Bioremediation- A Review: Exploring the Potential of Polycyclic Aromatic Hydrocarbons Degraders for Bioremediation

Abstract

Polycyclic aromatic hydrocarbons are carcinogenic to humans, animals, and plants. Polycyclicaromatic hydrocarbon concentrations have been steadily growing in the environment, including water,soil, air, sediments, marine water, and vegetables. The excessive use of polycyclic aromatichydrocarbon-containing petrochemical compounds for globalisation and industrialization, as well as thepolycyclic aromatic hydrocarbon's resistance to microbial degradation, are major factors contributing tohigher polycyclic aromatic hydrocarbon concentrations in the environment. A sustainable method will bethe formation of consortia of efficient polycyclic aromatic hydrocarbons degraders for the total removalof polycyclic aromatic hydrocarbons from polluted locations.The consortia formed by efficient polycyclicaromatic hydrocarbons digesting bacteria with new plasmids is effective for polycyclic aromatichydrocarbon bioremediation.
