Hydrocarbon contamination can be as a result of various sources such as; accidents during fuel transportation by trucks and ships; leaking of oil from underground storage tanks, extraction and processing oil. Interests about the possibility of water and soil contamination by oil and oil byproducts gains importance since they are one of the major pollutants in the environment. Petroleum hydrocarbon polluted areas can be treated through physical, chemical and biological methods. During cleaning up, microbial degradation processes aid the elimination of spilled oil from the environment after critical removal of large amounts of the oil by different physical and chemical methods. Therefore, this study aimed at isolating bacteria from diesel oil contaminated surface waters and measuring their degradation ability to use in the remediation processes. The catabolic genes and enzymes responsible for diesel oil degradation were also investigated in the bacteria. Presence of the enzymes alkane monooxygenase encoded by alkb and catechol 2, 3- dioxygenase encoded by C23O were confirmed in the bacteria isolated. 61-92% diesel oil degradation by t

Use of biodiesel byproduct crude glycerol as the carbon source for fermentation processes by recombinant Pichia pastoris
Celik, Eda; Ozbay, Nalan; OKTAR, NURAY; Çalık, Pınar (American Chemical Society (ACS), 2008-05-07)
The aim of this study is to investigate the efficiency of using crude glycerol, the main byproduct of biodiesel industry, directly in the production media of Pichia pastoris fermentation processes. Different biodiesel synthesis conditions were examined, that is, transesterifications of canola, corn, soybean, and sunflower oils, with pure methanol in a molar ratio of 1:6 or 1:3, using 1% or 0.5% (w/v) NaOH as the catalyst. Among these, canola oil-derived glycerol served as the most favorable carbon source, a...
Investigation on indigenous bacteria for individual BTEX degradation potentials and relative pathways used
Yavaş, Alper; İçgen, Bülent; Parlaktuna, Mahmut; Department of Biotechnology (2018)
Monoaromatic hydrocarbons including benzene, toluene, ethylbenzene and xylene collectively called as BTEX are found in the composition of crude oil and gasoline as an additive and thought to be the most serious contaminants of soil and groundwater. It is expected that indigenous bacteria isolated from petroleum hydrocarbon contaminated sites probably have degradation potential for the BTEX compounds. In this study, out of 22, 19 bacterial strains were selected as potential degraders for at least one of the ...
Characterization of oil shales by high pressure DSC
Kök, Mustafa Verşan; Pokol, Gy. (1999-01-01)
Pressurised differential scanning calorimeter (PDSC) has been used to obtain information on the pyrolysis and combustion characteristics of oil shales. Two distinct exothermic peaks were identified in combustion experiments known as low temperature oxidation (LTO) and high temperature oxidation (HTO) reaction regions. The pyrolysis process of all studied oil shale samples showed one exothermic effect at each total pressure studied. Kinetic data were analysed by Roger & Morris and Arrhenius methods and the r...
Characterization of lead-resistant river isolate Enterococcus faecalis and assessment of its multiple metal and antibiotic resistance
Aktan, Yasin; Tan, Sema; İçgen, Bülent (Springer Science and Business Media LLC, 2013-06-01)
Contamination of surface waters has a direct impact on the public health of entire communities. Microorganisms inhabiting contaminated surface waters have developed mechanisms of coping with a variety of toxic metals and drugs. Investigations were carried out to isolate and identify lead-resistant bacteria from the river KA +/- zA +/- lA +/- rmak along the city of KA +/- rA +/- kkale, Turkey. Of the 33 lead-resistant isolates, one isolate with a minimal inhibitory concentration of 1,200 mg L-1 was isolated ...
Modeling water quality impacts of petroleum contaminated soils in a reservoir catchment
Ünlü, Kahraman (2000-05-01)
Soil contamination due to spills or leaks of crude oils and refined hydrocarbons is a common problem. Estimation of spill volume is a crucial issue in order to determine the expected contaminating life span of contaminated soils. The direct procedure to determine the amount of hydrocarbon in soil is to measure the concentration of total petroleum hydrocarbon (TPH) in soil samples. The primary objective of this study was to assess the potential effects of oil contaminated soils on the water quality of Devege...
