Bioremediation of petroleum contaminated soils-A review

The state-of-the-art methodology and ecologically sound that uses biological processes naturally to thoroughly remove toxic pollutants. The usage of soil, sediments, water, other pollution products employing microorganisms for the degradation of harmful chemicals. The chemical components are also metabolized by microorganisms for production of carbon or methane dioxide, water and biomass. Otherwise, the pollutants may be converted into less toxic or harmless metabolites enzymatically. Both in situ and off field, bioremediation technologies can be adopted. In the event of in situ bioremediation, the polluted material is treated at the site while the contaminated material is extracted to be treated in another location. Bio ventures, landfills, bio areas, manure, bioaugmentations, and bio-stimulation are some examples of bioremediation technologies. Bioremediatory are classified as microorganisms that perform bioremediation functions. Bioremediation and other techniques have been used extensively in past and present to remediate the pollutants of petroleum hydrocarbons in soil. As bioremediation is costeffective, and leads to the full mineralization, bioremediation is an excellent way of handling these polluted sites. This paper explores bioremediation processes in the soil system, focusing on degradation of petroleum hydrocarbons. (c) 2020 Elsevier Ltd. All rights reserved.
