The invention relates to a novel microorganism, designated Sphingomonas sp. strain AD109, which is capable of selectively desulfurizing dibenzothiophene. The invention also includes isolated proteins and nucleic acid sequences obtained from this microorganism. In another embodiment, the invention provides a method of using this microorganism or enzyme preparations derived therefrom in the biocatalytic desulfurization of a fossil fuel containing organic sulfur compounds.

Sphingomonas biodesulfurization catalyst

The invention relates to the unexpected discovery that the removal of the sulfinate group from an organosulfinate compound can be improved in the presence of an effective amount of a Lewis acid. The invention includes a method of removing the sulfinic acid functional group from an organosulfinic acid compound, comprising reacting the organosulfinic acid compound with an effective amount of a Lewis acid.
