Genomics Approach to Bioremediation: Principles, Tools, and Emerging Technologies

Abstract

Petroleum hydrocarbons are known to be a major pollutant. The removal of such pollutants from the environment is a real-life issue. Bioremediation is a process that makes use of living systems especially microbes to the destruction of toxicants. And hence, it has become a popular approach for restoring clean ecosystems. Petroleum hydrocarbon-degrading bacteria are distributed worldwide and have the potential to utilize petroleum hydrocarbon compounds as carbon and energy sources. Distributed oil was incubated alone or with the addition of clean or oil-containing faeces to study biotransformation of components in crude oil dispersions in the presence of excrement from marine organisms. Higher nutrient levels in the saltwater where aromatic degradation occurs are thought to cause the impact of clean fecal material on aromatic molecules, whereas n -alkanes are expected to degrade more slowly due to bacteria's preference for excrement over these molecules. Recent improvements in the activation of substrate hydrocarbons have expanded scientific knowledge of novel biochemical processes and occurrences, with the fumarate-addition pathway serving as an example, as seen in oil fields and enrichment. The purpose of this research was to give a comprehensive review of the unique characteristics of microbial bio and bioaugmentation of petroleum hydrocarbons. © 2023 John Wiley & Sons, Inc.
