Composite nanolayer photocatalyst-biocatalyst Rhodococcus erythropolis R1 for desulfurization of dibenzothiophene
A nanolayer of composite and Rhodococcus erythropolis biocatalyst was studied for the first time for desulfurization of dibenzothiophene as a model sulfur compound and its performance was compared with that of composite and R. erythropolis alone. The nanolayer of composite was synthesized by sol-gel method from ferrous oxalate and zinc oxalate precursors coated on glass by spin coating techniqu...
متن کاملSulfur-selective desulfurization of dibenzothiophene and diesel oil by newly isolated Rhodococcus sp. strains.
New desulfurizing bacteria able to convert dibenzothiophene into 2-hydroxybiphenyl and sulfate were isolated from contaminated soils collected in Mexican refineries. Random amplified polymorphic DNA analysis showed they were different from previously reported Rhodococcus erythropolis desulfurizing strains. According to 16S rRNA gene sequencing and fatty acid analyses, these new isolates belonge...
متن کاملBioenergetic Aspects of Dibenzothiophene Desulfurization by Growing Cells of Ralstonia eutropha
The present study focuses on effects of initial pH on dibenzothiophene (DBT) desulfurization via 4S pathway by growing cells of Ralstonia eutropha. For so doing, temporal changes of biomass concentration, glucose as a sole carbon source, pH value, and 2-hydroxybiphenyl (2-HBP) formation have been monitored during the bioprocess. The biomass concentration has been modeled by the logistic equatio...

متن کاملImprovement of Desulfurization Performance of Rhodococcus erythropolis IGTS8 by Assembling Spherical Mesoporous Silica Nanosorbents on the Surface of the Bacterial Cells
MCM-41 mesoporous silica is synthesized based on a self assembly method, using a quaternary ammonium template, CTAB for the adsorption of sulfur compounds from model oil (1.0 mmol/l DBT in dodecane solution). Then the adsorption capability of MCM-41 assembled on the surface of bacterium Rhodococcus erythropolis IGTS8 is examined regarding the improvement of the biodesulfurization process of...
