Bioremediation by oil degrading marine bacteria: An overview of supplements and pathways in key processes

Chemosphere. 2022 Sep;303(Pt 1):134956. doi: 10.1016/j.chemosphere.2022.134956. Epub 2022 May 16.

Abstract

Oil spillage is one of the most common pollutants which brings greater economic loss and damage to the environment. The intensity and amount of the damage may vary depending on factors such as the type of oil, the location of the spill, and the climatic parameters in the area. As for any pollution management, the guidelines are Reduce, Re-use, Recover and Disposal. Amongst the other remediation processes, Bioremediation is amongst the most significant environmentally friendly and cost-effective approaches for marine biological restoration because it allows complex petroleum hydrocarbons in spilt oil to decompose completely into harmless compounds. Mainly, the necessity and essence of bioremediation were talked about. This review discussed the bacteria identified which are capable of degrading various oil related pollutants and their components. Also, it covered the various media components used for screening and growing the oil degrading bacteria and the pathways that are associated with oil degradation. This article also reviewed the recent research carried out related to the oil degrading bacteria.

Keywords: Bioremediation; Marine pollutant; Media composition; Methods; Oil degradation pathway; Oil spillage.
