Title:

ARTHROBACTER SP., AND ITS USE FOR DESULFURIZING FOSSIL FUEL

Document Type and Number:

Japanese Patent JP3853459

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To obtain a new cultured strain capable of selectively opening the C-S bonds of sulfurized organic molecules contained in fossil fuels without breaking carbonaceous structures and capable of selectively removing organic sulfur compounds contained in the fossil fuels.
SOLUTION: This new biologically pure cultured Arthrobacter sp. CBS 208.96 can selectively open the C-S bonds of sulfurized organic molecules contained in fossil fuels without breaking carbonaceous structures. The Arthrobacter sp. CBS 208.96 is useful for selectively removing organic sulfur compounds contained in fossil fuels, such as thiol compounds, thiophene compounds, benzothiophene compounds and dibenzothiophene compounds. The new strain is obtained by adding water to a soil stained with a crude oil having an organic sulfur content of approximately 6% and collected from a biologically improved pilot plant in order to isolate a microorganism strain capable of decomposing dibenzothiophene compounds, vigorously stirring the mixture, collecting the supernatant, culturing the supernatant in a culture medium, and subsequently selecting a colony capable of decomposing the dibenzothiophene compounds.
