Publisher Summary The petroleum refining companies have recognized the fact that hydro desulfurization units for the high extent of desulfurization are extremely expensive to build and operate. Therefore, as an alternating promising method to HDS, microbial desulfurization (MDS) that harnesses the metabolic processes of suitable bacteria to the desulfurization of fossil fuels has attracted attention of many researchers. Consequently, in recent years there has been considerable effort to develop… Expand
