The strain Sphingomonas sp. GY2B is a high efficient phenanthrene-degrading strain isolated from crude oil contaminated soils that displays a broad-spectrum degradation ability towards PAHs and related aromatic compounds. This paper reports embedding immobilization of strain GY2B in calcium alginate gel beads and the rapid degradation of phenanthrene by the(More)
Density functional theory (DFT) calculations were carried out at the B3LYP/6-31G(d) level for all polychlorinateddibenzo-p-dioxins and dibenzofurans (PCDD/Fs). Mulliken atomic charge on chlorine atom (QCl(n)) and molecular total energy (ET) were adopted as the theoretical indicators of the dechlorination reaction activity. The hypothesis was that the(More)
This study described the development of a method based on Soxhlet extraction combining high performance liquid chromatography (Soxhlet-HPLC) for the accurate detection of BDE-209 in soils. The solvent effect of working standard solutions in HPLC was discussed. Results showed that 1:1 of methanol and acetone was the optimal condition which could totally(More)
