| 中文摘要 | Several parameters that influence the dibenzothiophene (DBT) desulfurization by lyophilized cells of Pseudomonas delafieldii R-8 were studied in the presence of dodecane. The aqueous media tested with pH range in 4.6-8.5 made no obvious difference on the desulfurization activity. The rate and extent of desulfurization were strongly dependent on the volume ratio of oil-to-water, DBT concentration and the cell concentration. The specific desulfurization rate of DBT and 4,6-dimethyl DBT (4,6-DMDBT) could reach 11.4 and 9.4 mmol sulfur kg(-1) dry cells (DCW) h(-1), respectively. The desulfurization pattern of DBT was represented by the Michaelis-Menten equation. The kinetic parameters, the limiting maximal velocity (V-max) and Michaelis constant (K-m), for desulfurization of DBT were calculated. (C) 2002 Elsevier Science B.V. All rights reserved. |
