The presence of sulfur in coal and petroleum contributes to corrosion of production and refining equipment and burning these high-sulfur products emits sulfur oxides to the atmosphere. Microorganisms that can enzymatically release organically bound sulfur from organic components of coal or petroleum or from dibenzothiophene (DBT) could reduce the sulfur content of high sulfur fuels without depleting their British thermal unit value. Two major pathways for microbial metabolism of DBT have been proposed. Some of the genes for the DPT degradative pathway have been isolated and characterized. However, no genes for the desulfurization pathway have been identified. This paper reports the isolation from Rhodoccus sp. strain IGTS8 pf a set of genes that confer a specific desulfurization phenotype to mutants and to a related organism, R. fascians D188-5, that is normally unable to desulfurize DBT. 38 refs., 2 figs., 1 tab.
