Combination of a crude oil-degrading bacterial consortium under the guidance of strain tolerance and a pilot-scale degradation test

The Beneficial Roles ofPseudomonasin Medicine, Industries, and Environment: A Review

“…Eliminating or limiting these adverse effects from crude oil spillage situations implies total prevention of the spillage where possible and amending the soil via the procedure known as bioremediation [41]. Some known methods used in remediating crude oil-polluted soils include physical separation, chemical degradation, photodegradation, and bioremediation [42]. However, bioremediation is gaining preference because of its comparative effectiveness, relatively lower costs, and eco-friendliness when compared to other techniques.…”

Bioremediation: Data on biologically-mediated remediation of crude oil (Escravos Light) polluted soil using Aspergillus niger

“…Soil amendment technologies, known as remediation, include physical separation, chemical treatments, photodegradation and biologically-mediated remediation (bioremediation) but among these the use of bioremediation techniques is attracting preference [7,10,[14][15][16]. This is due to the combined advantages of relatively lower cost, higher effectiveness and resultant lower adverse impacts on the ambient environment, ensuing from the use of bioremediation instead of the other methods that could rather lead to further environmental-toxicity [7,10,[16][17].…”

“…detoxification, of the recalcitrant hydrocarbon pollutants from oil spills [7,13,[15][16]. In spite of these advantageous potentials of bioremediation usage, problem persists from the consideration that contaminating pollutant removal efficiencies from different biological species or organisms that could be used for bioremediation are highly variable [10,[15][16]. Also, while studies have proposed the use of fungi species, including Aspergillus spp., among useful microorganisms for oil polluted soil bioremediation [2, [11][12]15,18] no dataset exists on Aspergillus niger usage for bioremediation of raw and treated crude oil polluted soil.…”

“…This is due to the combined advantages of relatively lower cost, higher effectiveness and resultant lower adverse impacts on the ambient environment, ensuing from the use of bioremediation instead of the other methods that could rather lead to further environmental-toxicity [7,10,[16][17]. The technique of bioremediation exhibits these potencies from the abilities of employing metabolic activities of animals, plants and microorganisms for removal or conversion from toxic to non-toxic compounds, i.e.…”

“…The discharge of this liquid petroleum hydrocarbon into marine (offshore) or land (onshore) is toxic/injurious to living biota in the ecosystem of the spill even as it exhibits potential risks of normal soil processes interference, fire hazards and further contaminations of air and water [1][2][3][4][5][6][7][8]. Oil spills by any of accidental leakages, material ruptures or improper handling from production installations such as the well-heads leading to raw crude oil spillage, or from flow lines towards storage and refinement, after the removal of impurities, which translates to treated oil spillage [9][10][11]. Hydrocarbons, the major constituents from petroleum, persists in the environment as recalcitrant contaminants of which removal and treatments are highly problematic and constitute challenges to stakeholders and researchers globally [10,[12][13].…”
