The essence of cleaner and greener fuel involves the removal of organosulfur compounds from fossil fuels so as to lower the sulfur oxide emissions upon their combustion. The situation becomes more serious globally as the depleting fossil fuel reservoirs have increased sulfur content with recalcitrant compounds that resist the hydrodesulfurization process used in the refineries. Alternative desulfurization strategies have gained impetus, biodesulfurization (BDS) being one of them. However, the use of microbes for BDS is challenging mainly because of the numerous hydrocarbons present in fuels...

Biodesulfurization (BDS) of fossil fuels has emerged as a promising alternative to the conventional hydrodesulfurization process for containment of sulfur oxide emissions during fuel combustion. The 4S pathway is a sulfur specific pathway that removes the sulfur atom from the recalcitrant organosulfur compounds present in fossil fuel fractions like diesel by oxidation. The end product is a sulfurless molecule, 2-hydroxybiphenyl. Though the process is very specific, however, speculations as to the bacteriums organic solvent tolerance for effective BDS process are justified. This book focuses...
