Gordona sp. CYKS1 (KCTC 0431BP) capable of desulfurizing fossil fuel containing organic sulfur compounds

Abstract

The present invention relates to Gordona sp. CYKS1 (KCTC 0431BP) capable of selective removal of organically bound sulfurs from carbonaceous fossil fuel such as petroleum and coal by cleaving bonds between carbon and sulfur atoms in the said sulfur-containing organic compounds, and a method for biological desulfurization using this strain at the room temperature and atmospheric pressure. Since Gordona sp. CYKS1 (KCTC 0431BP) utilizes various organic sulfur compounds in fossil fuel besides dibenzothiophene as a sole sulfur source, the method for biological desulfurization employing the Gordona strain has advantages over the conventional chemical methods as followings: The desulfurization can be carried out at a mild condition; the cost for installation and operation of equipments can be reduced; and, the desulfurization of highly complex organic sulfur compounds can be realized.
