Bacterial Biological Factories Intended for the Desulfurization of Petroleum Products in Refineries

The removal of sulfur by deep hydrodesulfurization is expensive and environmentally unfriendly. Additionally, not separated completely from heterocyclic poly-aromatic compounds. In nature, several microorganisms (Rhodococcus erythropolis IGTS8, Gordonia sp., Bacillus Mycobacterium Paenibacillus sp. A11-2 etc.) have been reported to remove petroleum fractions. All these microbes recalcitrant organosulfur compounds via the 4S pathway, showing potential for some only. Activity up 100 µM/g dry cell weights needed meet current demand desulfurization. present review describes desulfurization capability various acting on kinds sources. Genetic engineering approaches other species revealed a variety good substrate ranges desulfurization, both aliphatic aromatic Whole genome sequence analysis pathway inhibition pTeR group inhibitor also discussed. Now, emphasis being placed how commercialize industrial-level applications incorporating biodesulfurization into systems. Thus, this summarizes potentialities petroleum. information included in could be useful researchers as well economical commercialization bacteria industries.
