AN ARTICULATED OVERVIEW ON DEVELOPED TRENDS IN BIOREMEDIATION OF COMPLEX HYDROCARBON CONTAMINATION

Biochemical Engineering

Fuel is a major source of energy for sustenance of human life and this energy is obtained in the form of crude from the earth’s crust. In order to obtain energy from earth’s crust, it is recovered from the ground followed by drilling, sucking and extracting from underground. The contamination of fertile land occurs due to anthropogenic activities such as the spillage of crude after the decommissioning of the oil recovery machinery after recovery process, while recovering oil through artificial lift or naturally, transportation, etc. This leads to the exploitation of natural resources. This can be reclaimed again into clean and fertile land by giving proper remediation treatment to soil that is contaminated with Poly Aromatic Hydrocarbons. The method of reclamation involves different kinds such as, physical, chemical and biological methods. The biological method again involves several of its types and kinds. It was proved in literature that the biological method is the most reliable and environment friendly hence acquired considerable significance. Bioremediation is a technique that uses non-pathogenic environment friendly microorganisms to remediate contaminated soil. The significance of bioremediation is stated by certain observations resulted from experiments that are carried out in literature. The effect and applications are observed from studies till date an briefly articulated in current document.
