FREMGANGSMAATE VED SELEKTIV FREMSTILLING AV MIKROORGANISMER SOM ER I STAND TIL AA REDUSERE SVOVEL I KULL OG FREMGANGSMAATE VED MIKROBIELL DESULFURERING AV KULL

摘要

A process for the preparation of microorganisms, ATCC No. 39327 which are capable of reproducible reduction of sulfur, particularly organic sulfur, in coal wherein the novel microorganisms are grown in situ enriched with sulfur compounds and subsequently grown in the presence of a coal substrate and nutrient medium while maintaining an essentially neutral pH. Contacting an aqueous coal slurry with the novel microorganism of the present invention provides coal having reduced organic sulfur content.
