The biodesulfurization of nine coals was examined by use of Thiobacillus. ferrooxidans, and the factors which affect the efficiency of biodesulfurization were investigated. The % removal of inorganic sulfur varied from 23-90% depending upon the type of coal. The pH increase in the medium was caused by the leaching of Ca from coal, and the % removal of inorganic sulfur was decreased. The prediction method for biodesulfurization efficiency was developed by use of acid leaching test (0.1M HNO_3). Also the removal of hazardous trace elements, such as As and Hg, from coal during biodesulfurization process was examined.
