the combustion of sulfur-rich fossil fuels leads to the release of acid rain-causing sulfurdioxide into the environment. the aim of this study was to enhance the efficiency of biodesulfurizationusing pseudomonas aeruginosa through the duplication of the dsz cluster in this organism. one copy ofthe dsz cluster was inserted by a tri-parental mating method into the chromosome of pseudomonasaerugin...

There are several problems limiting an industrial application of fossil fuel biodesulfurization, and one of them is the cost of culture media used to grow the microorganisms involved in the process. In this context, the utilization of alternative carbon sources resulting from agro-industrial by-products could be a strategy to reduce the investment in the operating expenses of a future industria...

Sulfur content in fossil fuels is known to be the most important anthropogenic cause of sulfur oxide emissions to the atmosphere. In order to avoid health, environmental and technical problems caused by this compound, legislation imposes restrictive limitations to fuel sulfur content. Biodesulfurization (BDS) can become a complementary technology to hydrodesulfurization (HDS) to face this situa...

Desulfurization of fossil fuels demands a high technology as the crude oil is very complex mixture of molecules with a largest hydrocarbons form in composition. Hydrogenic method for desulfurization, takes higher cost and energy and also sulfur is not separated completely from heterocyclic poly-aromatic compounds. Researchers are focused on the use of microbial desulfurization [Biodesulfurizati...

Petroleum contains many heterocyclic organosulfur compounds refractory to conventional hydrodesulfurization carried out with chemical catalysts. Among these, dibenzothiophene (DBT) and DBTs bearing alkyl substitutions are representative compounds. Two bacterial strains, which have been identified as Paenibacillus strains and which are capable of efficiently cleaving carbon-sulfur (C--S) bonds i...

Fossil fuels are the main sources of human energy, but their combustion releases toxic compounds sulfur oxide. In oil industry, using optimal methods to eliminate from fossil is a very important issue. this study, performance montmorillonite/graphitic carbon nitride (a new hybrid nanostructure) in increasing biodesulfurization activity Rhodococcus erythropolis IGTS8 was investigated. X-ray diff...
