Microbial Bioremediation Techniques for Polycyclic Aromatic Hydrocarbon (PAHs)-a Review

摘要

This review summarizes current knowledge of the polycyclic aromatic hydrocarbons (PAHs) contaminant in the environment and the importance of using benzo(a)pyrene in this study. It highlights the removal techniques in eliminating the PAHs and their limitations on the bioremediation method. The factors that affect the remediation were thoroughly explained in this paper, focusing on removing PAHs using bioremediation. The remediation methods using bacteria and fungi have emerged as the potential degrader of PAHs pollutants and are being extensively studied to evaluate the best removal conditions. The PAHs degradation pathways have also been discussed in this paper to provide insight on microbial bioremediation in reducing PAHs.
