This is when petroleum degrading bacteria and archaea are able to mediate oil spills most efficiently. Weathering and environmental factors play large roles in the success of bioremediation. Interacting soil and pollutant chemicals truly account for the work that can be completed by these microorganisms.
Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), heterocyclic compounds (such as pyridine or quinoline ...
Bioremediation of oil contaminated soils, marine waters and oily sludges in situ is a feasible process as hydrocarbon degrading microorganisms are ubiquitous and are able to degrade most compounds in petroleum oil. In the simplest case, indigenous microbial communities can degrade the petroleum where the spill occurs.
Hydrocarbon-degrading bacteria have many different applications but has specially importance their role in the field of environmental microbiology. [35] Marine hydrocarbonoclastic bacteria are powerful tools for bioremediation, as they can degrade and convert contaminant oils because of their catabolic versatility. [36]
Bioremediation can be carried out by bacteria that are naturally present. In biostimulation, the population of these helpful bacteria can be increased by adding nutrients. [6] [15] Bacteria can in principle be used to degrade hydrocarbons. [16] [17] Specific to marine oil spills, nitrogen and phosphorus have been key nutrients in biodegradation ...
This process, overall, is referred to as bioremediation and is an EPA-approved method for reversing the presence of oil or gas spills. While biostimulation is usually associated with remediation of hydrocarbon or high production volume chemical spills, it is also potentially useful for treatment of less frequently encountered contaminant spills ...
The Sun Oil pipeline spill in Ambler, Pennsylvania spurred the first commercial usage of in situ bioremediation in 1972 to remove hydrocarbons from contaminated sites. [6] A patent was filed in 1974 by Richard Raymond, Reclamation of Hydrocarbon Contaminated Ground Waters, which provided the basis for the commercialization of in situ bioremediation.
[1] [5] In 1947, ZoBell and colleagues set the basis of petroleum microbiology applied to oil recovery, whose contribution would be useful for the first MEOR patent granted to Updegraff and colleagues in 1957 concerning the in situ production of oil recovery agents such as gases, acids, solvents and biosurfactants from microbial degradation of ...
