Microbial action to remediate petroleum-hydrocarbon contaminated soil
Author(s): Sohani Das and Rupesh Dutta Banik
Abstract: The primary energy source for many companies and daily living is petroleum. Priority pollutants include hydrocarbons, which are a major component of petroleum pollution. Oil spills and other accidental releases of petroleum-derived chemical wastes into the environment that poses the contamination of soil, sediments, and marine environments, frequently have detrimental effects on human health. It is reported that petroleum hydrocarbons alter the genetic sequences that leads to mutation and more importantly it exhibits carcinogenic effects also. They also have detrimental socio-economic effects in the host communities that produce the oil. In comparison to the conventional physico-chemical procedures for the restoration and reclamation of polluted areas, bioremediation strategies have been recognised as an economical and environmentally benign alternative. Depending on the contaminants in the polluted soil, different organisms are used with various bioremediation techniques. Microbial bioremediation is the technique of using microorganisms or microbial processes to remove or degrade pollutants from soil. Extracellular enzymes are produced by microbes to break down complex hydrocarbons into smaller, more accessible molecules. These compounds are subsequently transferred into microbial cells to provide energy and growth. Microbes frequently build biofilms on soil particles, resulting in localised microenvironments that improve degradation efficiency and shield cells from harmful circumstances. This paper contrasts the degradative properties of remediation techniques depending on microbial action.
