More Information
Summary:PURPOSE: A process for desulfurizing fossil fuel and sulfur-containing wastes by fixing sulfur-oxidizing bacteria to a carrier and contacting with fossil fuel is provided which improves the reusing efficiency of a biocatalyst and desulfurization efficiency of total processes and enables to separate and recover oil fractions easily after treatment. CONSTITUTION: A sulfurizing method using microorganism comprises setting Sulfur-oxidizing bacteria as one selected from the group of Gordona sp. CYKS1 strain (KCTC 0431BP), Nocardia sp. CYKS2 strain (KCTC 0432BP), Rhodococcus sp. IGTSB and Rhodococcus sp. H-2 to a carrier and subjecting to contacting with fossil fuel and sulfur-containing wastes at 25 to 40°C for 3 hr to 3 days. The carrier is selected from celite, chitosan and gelatin.
