“…Overall, Dietzia sp. CN-3 was able to grow at pH between 5 and 10, with an optimal pH of 7.0, at which Dietzia has the highest enzymatic activity for degradation of the saturated hydrocarbons in crude oil (Duckworth et al, 1998;Wang et al, 2007;Yumoto et al, 2002).…”

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.

“…Many immobilized microorganisms have been successfully used for bioremediation of crude oil (Liang et al, 2009). Considering the broad chioces, low cost, simple process and less impact on microbial activity (Oh et al, 2000;Lee et al, 2010), immobilization have been proved to be an effective strategy to apply functional microorganism for bioremediation (Wang et al, 2007;Mollaei et al, 2010).…”

a b s t r a c tUsing enrichment culture technique, two isolates that brought a significant degradation and dispersion of crude oil were obtained from contaminated sediments of the Bohai Bay, China. 16S rRNA gene sequencing and phylogenetic analysis indicated that the two bacterial strains affiliated with the genera Vibrio and Acinetobacter. Subsequently, the bacterial cells were immobilized on the surface of cotton fibers. Cotton fibers were used as crude oil sorbent as well as a biocarrier for bacteria immobilization. Among the two isolates, the marine bacteria Acinetobacter sp. HC8-3S showed a strong binding to the cotton fibers, possibly enhanced through extracellular dispersant excreted by Acinetobacter sp. HC8-3S. Both planktonic and immobilized bacteria showed relatively high biodegradation (>60%) of saturated hydrocarbons fraction of crude oil, in the pH range of 5.6e8.6. The degradation activities of planktonic and immobilized bacteria were not affected significantly when the NaCl concentration reached 70 g/L. The immobilized bacterial cells exhibited an enhanced biodegradation of crude oil. The efficiency of saturated hydrocarbons degradation by the immobilized bacterial cells increased about 30% compared to the planktonic bacterial cells.

“…Biological treatment of phenols has been an increasingly important process in pollution control [2], [19], [20]. Moreover, compared with physico-chemical methods, the biodegradation method of phenols removal is a more environmental friendly and cost effective alternative, universally preferred, because of the possibility of complete mineralization of phenol [2], [11], which results in complete conversion of a compound to its inorganic mineral constituents [1].…”

Abstract-Batch experiments were carried out to examine the biomass acclimatization during the aerobic biodegradation of 2, 4 dichlorophenol (2, 4 DCP) by Pseudomonas putida immobilized in polyvinyl alcohol (PVA) gel pellets in a bubble column bioreactor. The bacteria was acclimatized to 2, 4 DCP with concentrations of up to 200 mg/l, with and without the addition of glucose. After the acclimatization, experiments were carried out with initial 2, 4 DCP concentrations ranging from 25 to 100 mg/l. In the course of the study, a phenomenon was noticed that can be related to the effect of carbon starvation on the biodegradation ability of the bacterial cells. This paper presents the results on this phenomenon. Starved cells showed higher growth and degradation rates.
