“…The concentration of residual oil was determined using an infrared spectrometric oil detector (OIL 460, Beijing China Invent Instrument Tech. Co., Ltd, China) (Liang and Tilotta, 2003). The crude oil components, including saturated hydrocarbons, aromatic hydrocarbons, resins and asphaltenes, were separated using the column chromatography method (Head et al, 2006).…”

a b s t r a c tA bacterial strain, CN-3, was isolated from petroleum-contaminated sediment in Bohai Bay, China. Morphological, physiological and phylogenetic analyses indicated that the strain belonged to the genus Dietzia. It was capable of utilizing a wide range of alkanes (C 14 eC 31 ), aromatic compounds and crude oil as the sole carbon and energy sources. The bacterium showed high degradation rate (>80%) of the saturated hydrocarbons of crude oil in the pH range of 6e9. The degradation rate was hardly affected at a NaCl concentration up to 85 g L À1 , indicating that the strain can tolerate high salinities. The real-time quantitative Polymerase Chain Reaction (PCR) results showed that the CYP153 genes could be significantly induced by C 14 , C 15 , C 16 , C 26 and pristane, whereas the transcription level of alkB gene was increased moderately with C 14 , C 15 , C 16 , C 26 and pristane induction condition. A high degradation extent, wide substrate range and facile conditions enhanced the potential for this bacterial strain to be used in the bioremediation of crude oil pollution.

“…Amador-Hernández and Luque de Castro [14] have reviewed prior works using on-line detection for SFE, including also UV-Vis and prototypes such as NMR and MS. Primarily, continuous monitoring using above mentioned setups has been applied to extraction of plant matrices [15,16] and detection of lipids in water or soil [17,18] to mention a few examples.…”

“…Pollutant concentration in aqueous phase had a positive correlation with sand content, that is, it increased generally with the amount of sand. Petroleum is a mixture composed of many different compounds [10] , and it has the characteristics of low specific gravity, high viscosity, and low water solubility. Its existing state in water is different from other soluble pollutants, besides the small quantity of petroleum components dissolves in water, the major part is emulsified oil and floating oil.…”

The desorption characteristics of the petroleum pollutants in oil-contaminated chernozem was researched in the process of exploring the interaction between crude oil pollutants and the typical soil in Daqing oilfield. The oscillation-equilibrium method was used in desorption experimental simulation. Desorption kinetics of petroleum pollutants, desorption effect of suspended particles concentration, and the influences of pH, temperature on adsorption action were investigated by the experiments. Results showed that the release velocity of petroleum pollutants was rapidly in the first few minutes, however the desorption process approached to balance gradually in 1-2 hours and attained balance completely after 3 hours. In addition, the balanced desorption capacity of the chernozem ascended gradually when desorption process achieved balance, with the increase of pH, concentration of suspended particles and temperature. The chernozem soil had weak desorptive ability to the crude oil pollutants in the Daqing oilfield.
