摘要
The invention provides a novel flavin reductase, which has been isolated from Rhodococcus strain sp. IGTS8 and purified to homogeneity. The flavin reductase is of use in the biocatalytic desulfurization of a fossil fuel containing organic sulfur compounds. The method comprises the steps of: (1) contacting the fossil fuel with an aqueous phase containing a biocatalyst capable of cleaving carbon-sulfur bonds and a rate-enhancing amount of the flavin reductase of the present invention, thereby forming a fossil fuel and aqueous phase mixture; (2) maintaining the mixture under conditions sufficient for cleavage of the carbon-sulfur bonds of the organic sulfur molecules by the biocatalyst, thereby resulting in a fossil fuel having a reduced organic sulfur content; and (3) separating the fossil fuel having a reduced organic sulfur content from the resulting aqueous phase.
