Migration of N-Alkanes from Diesel Oil along the Bacteria-Ciliates Trophic Chain
      
The data on the dynamics of the content and qualitative composition of intracellular alkanes in Paramecium caudatum Ehrenberg, 1838 cells feeding on bacteria with different levels of exposure to diesel oil are presented.
      
The possibility of migration of alkanes from diesel oil along the trophic chain from bacteria to ciliates was demonstrated.
      
The radiation-chemical purification of water from petroleum products (diesel oil, motor oil, and residual fuel oil) was studied by gas chromatography-mass spectrometry.
      
Oxidation of Diesel Oil in the Presence of Metallic Copper
      
The kinetic parameters of autooxidation of DL-0.2 diesel oil in the presence of copper were determined in the range 120-140°C.
      
The possibility of using Ionol for stabilization of diesel oil under these conditions was studied.
      
A study was carried out of extractive refining of atmospheric gas oil with N-methylpyrrolidone in the presence of undecane to remove aromatic hydrocarbons and sulfur-containing compounds and thus obtain a summer diesel oil component.
      
The addition of CNSPs to carbon black (catalyst support) could improve hydrodesulfurization performance of carbon supported Ni-W catalysts for diesel oil.
      
Bacterial strains were selected from a desiccated polluted soil for their drought tolerance and their ability to grow on diesel oil in view of incorporating them in a bioaugmentation product.
      
These strains grow on the easily degradable components of diesel oil.
      
In Brazil, a national program was launched in 2002 to evaluate the technical, economic, and environmental competitiveness of biodiesel in relation to the commercially available diesel oil.
      
Induction of ascospore formation in hydrocarbon utilizing ascosporogenous yeasts was observed during the growth of the yeasts on gas oil, diesel oil, white kerosene and n-alkanes.
      
Holdfasts at this site were filled with sediment containing traces of diesel oil, and the macrofaunal community was dominated by opportunistic worms.
      
Initial diesel oil contamination of 4000?mg?kg-1 soil dry matter (dm) was reduced to 380-400 mg?kg-1 dm after 155?days of incubation.
      
In both soils, about 30?% of the diesel oil contamination (1200 mg?kg-1 dm) was eliminated by abiotic processes.
      
A comparison of SPME and pentane extraction of diesel oil was made and found to be consistent.
      
These compounds were approximately 3% of the total hydrocarbons in the diesel oil used and remained undegraded throughout the study although none of the chemical or physical parameters was limiting.
      
Naphtho[2,1-b]thiophene (NTH) is an asymmetric structural isomer of dibenzothiophene (DBT), and NTH derivatives can be detected in diesel oil following hydrodesulfurization treatment, in addition to DBT derivatives.
      
Biodegradation of hydrocarbon cuts used for diesel oil formulation
