The Impact of Oil Contamination on Soil Ecosystem In assessing the environmental situation relating to oil contamination, it is important not only to determine the spread of pollution, but also the depth of its penetration (Rogozina, ; Pikovskiy, ). Assay of crude oil degradation in liquid medium The crude oil degradation capability of both bacterial strains was analyzed by liquid medium. Among this study highest crude oil degradation were noted in Pseudomonas putida (55 %) compared than Bacillus cereus (40 %). The results were showed in Table 6, Figure 3.
The degradation capacity of any microbial culture is not necessarily the result of merely adding the capacities of the individual strains (Ghazali et al., ). As the usage of petroleum hydrocarbon products increase, soil contamination with engine oils is becoming one of the major environmental problems. To remediate. percentage degradation of crude oil at 37oC by E. coli K12 DH1 transformed with the plasmid DNA from Klebsiella pneumoniae was % while that transformed with the plasmid DNA from Serratia marscencens degraded % of the crude Size: KB.

[F D Cook; D W S Westlake] -- Results of continued field and laboratory studies of the factors affecting the microbiological degradation of crude oils primarily originating in the northwest Northwest Territories.

by: 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.
Crude oil was introduced, in microcosm systems, after physical weathering ( × g, 25 °C for 48 h); crude oil was supplemented with % (v/v) of squalene (C 30 H 50, Sigma-Aldrich, Milan) as internal spike for measure of bio-degradation by: Biodegradation of crude oil in subsurface petroleum reservoirs has adversely affected the majority of the world’s oil, making recovery and refining of.
Accordingly, nitrogen had been related with the microbial growth and is commonly catalogued as limiting nutrient during crude oil degradation in natural environments . Moreover, the. Microbial Degradation of lubricating oils onboard. One of the vessel I served as Second Engineer suffered a sudden microbial degradation and infestation which caused USD on engine repair and a 30 days of laid up with further consequent losses.

Apr; 27 (4)– Fredrickson JK, Hicks RJ, Li SW, Brockman FJ. Plasmid incidence in bacteria from deep subsurface sediments. Appl Environ by: Dennis P. Nolan, in Handbook of Fire and Explosion Protection Engineering Principles for Oil, Gas, Chemical, and Related Facilities (Fourth Edition), Petroleum or crude oil is a naturally occurring oily, bituminous liquid composed of various organic chemicals.
It is found in large quantities below the surface of the Earth and is used as a fuel and a raw material (feedstock). An experimental study was undertaken to assess the efficiency of Pseudomonas aeruginosa, Bacillus subtilis, and Acinetobacter lwoffi isolated from petroleum contaminated water and soil samples to degrade crude oil, separately and in a mixed bacterial consortium.
Capillary gas chromatography was used for testing the effect of those bacterial species on the Cited by: Crude oils Two diﬀerent crude oils (nos. 1 and 2) were used for degradation experiments.
Both consisted of linear and branched alkanes (pristane and phytane) and diverse aromatic components (e.g. toluene, xylenes, ethylben-zene, (methylated) naphthalenes, dibenzothiophenes, phenanthrenes, and acenaphthenes) in varying by: Cook FD, Westlake DWS () Microbiological degradation of northern crude oils.

Table 2 Percentage of n-alkane degradation in crude oil by strains in this study after 15 days of incubation at 22 ± 1 °C with shaking ( g).
Table Top, bacterial culture s in natural sea water; Table Lower, Bacterial cultures performed in natural seawater with inorganic nutrients. Biodegradation of crude oil in surface environments results in similar changes in crude oil composition and the loss of saturated and aromatic hydrocarbons, together with an increase in the relative abundance of the polar fractions (which are more resistant to biodegradation), is a characteristic signature of crude-oil by: Microbiological analyses by isolation and identification using appearance factors were conducted on the biofilms formed.

Corrosion File Size: KB. Methanogenic oil degradation, on the other hand, does not require external electron acceptors and leads to less overall souring of the oil reservoir.
Several studies have described in vitro methanogenic degradation of crude oil related compounds [19, 20] Jones et al., ), including n-alkanes [21, 20] and aromatic by: 5.
Enzymes Participating in Degradation of Hydrocarbons. Cytochrome P alkane hydroxylases constitute a super family of ubiquitous Heme-thiolate Monooxygenases which play an important role in the microbial degradation of oil, chlorinated hydrocarbons, fuel additives, and many other compounds .Depending on the chain length, enzyme systems are required to introduce Cited by: Microbial degradation of crude oil Biodegradation of petroleum hydrocarbons is a complex process that depends on the nature and on the amount of the hydrocarbons present.
Hydrocarbons in the environment are biodegraded primarily by bacteria, yeast, and fungi. mixed populations with overall broad enzymatic capacities are required to degrade. The physical, chemical and microbiological characteristics of the soil across the western Niger Delta area of Nigeria were determined to assess its potential for natural remediation of crude oil pollution.
The pH (oil-producing area, ± ; non-oil producing, ± ) and temperature (28–35 °C in both areas) were favourable to natural remediation, while Cited by: 4.
Biodegradation is a cheap and environmentally friendly process that could breakdown and utilizes heavy crude oil (HCO) resources. Numerous bacteria are able to grow using hydrocarbons as a carbon source; however, bacteria that are able to grow using HCO hydrocarbons are limited.
In this study, HCO degrading bacteria were isolated from an Omani .Leahy JG and Colwell RR (). Microbiological degradation of hydrocarbons in the environment.
