The presence of sulfur in coal appears in three basic forms; as sulfates (mostly gypsum), pyrite and organic sulfur. Only pyritic sulfur can be separated from coal in coal preparation plants. Pyritic and organic sulfur may each constitute as much as 40 to 60% of the total removal of total sulfur content, respectively. Thus, removal of an effective portion of this sulfur content prior to coal combustion would substantially reduce the emission of sulfur oxides into the atmosphere. Many grades of coal and petroleum contain large quantities of sulfur compound which form corrosive air and water pollutant products during combustion. Since high temperature, high pressure or corrosion resistant equipment are not required for biological process, inexpensive construction materials can be used leading to low capital costs. Moreover, biological treatment is not likely to significantly alter the structure and the composition of the coal or to substantially reduce the BTU value of the coal. In this paper advantage process were discussed and introduced some effective microorganisms such as M. phlei and mesoacidophilic<\div>
