“…Furthermore, volatilization of lighter n-alkanes at colder temperatures may decrease. Atlas (1981) found that degradation was an order of magnitude greater at 25 • C compared with 5 • C, while Sexstone et al (1978) found diesel contamination in Arctic soils 28 years after the spill. Ludzack and Kinhead (1956) found that motor oil was rapidly oxidized at 20 • C, but not at 5 • C. Margesin and Schinner (2001) found that diesel degradation at a cold, high-altitude location occurred mostly during the summer and at a muchreduced rate.…”

“…24 Evidence was also found for biodegradation of oils applied in northern Canada, extensive microbial utilization of n-alkanes was measured. 25 On the other hand, greatly restricted rates of biodegradation were observed in northern soils 26 and after an oil spill into the ice-laden waters of Melville Bay in western Greenland. 16 Mulkins-Philipps and Stewart 27 demonstrated the presence of hydrocarbon-utilizing microorganisms in sediments and adjacent waters from Bermuda, Canadian northwest Atlantic and eastern Canadian Arctic marine shorelines; the frequency of speci®c hydro-carbon utilization in decreasing order was hexadecene, pristane, hexadecane, dibenzothiopene, anthracene and decalin.…”

The decontamination of oil-polluted cold environments has been recognized as an area of particular importance. The biodegradation of petroleum hydrocarbons at low temperatures has been reported in a variety of soil, water and marine systems in arctic, alpine and antarctic environments. Physical, chemical and biological factors contribute to hydrocarbon loss or alteration. Cold-adapted indigenous microorganisms are of essential importance for the biological decontamination of cold climates. Enrichments of oil-degrading microbial communities occur soon after oil contamination. Bioremediation, the acceleration of the natural biodegradation rate through the modi®cation of environmental conditions, has been studied in cold arctic, alpine and antarctic environments. Biostimulation by the addition of inorganic nutrients results in an enhanced oil degradation by the indigenous microorganisms, whereas bioaugmentation with oil-degrading cold-adapted microorganisms was sometimes reported to be unsuccessful. The effect of temperature on oil biodegradation and ecological consequences of oil spills are discussed. By using biological decontamination, the contaminant concentration cannot be reduced to zero.

This study aims to develop certain perspectives based on the principle of on-site remediation of the soil through biological means known as "bioremediation" against soil pollution issues resulting from fuel contamination in our country and to reveal the fatty acid profile in the final soils. The fatty acid profile of the soils was pointed out by testing the activity of three basic bioremediation applications (biological multiplication, biological excitation and the combined application of these two approaches) established in the laboratory condition. Under biological multiplication applications, six of the selected bacterial strains (Pseudomons aeruginosa, Pseudomonas putida biotype A, Citrobacter amalonaticus-GC subgroup A, Acinetobacter genomospecies) exhibit the highest growth in crude oil environment isolated from oil-contaminated soils of Adana, Batman and Adıyaman, and they also have the highest levels of crude oil degradation. Under biological excitation applications, the organic materials being humic-fulvic acid and, in combined applications, different combinations of bacteria mixture and organic materials were examined as to the amount of crude oil they degrade in an incubation period of 120 days by qualitative hydrocarbon-type analyses. The highest level of oil degradation, being 56%, occurred under biological multiplication applications where the bacteria mixture was applied. Under biological excitation conditions where various organic materials were applied to the contaminated soil, degradation to 18% was observed. In combined applications, oil degradation was achieved to 30%. The most common fatty acids were found to be 15:0 iso, 15:0 anteiso, 16:0, 16:1 w7c, 17:0ai, 18:2w6,9 and 18:1w9c fatty acids detected in both unpolluted and oil-contaminated soils. Determination of high level 18:1w9c fatty acid in oil contaminated and clean soils may indicate the presence of Pseudomonas spp. However, fatty acid 15:0 anteiso was determined to be higher in oil-contaminated soils than in unpolluted soils. It may be explained that Gram positive bacteria were predominant in oil-contaminated environment.
