	%X Biological processes based on oxidation of sulfur
compounds by chemolithotrophic microorganisms are emerging as an
efficient and eco-friendly technique for removal of sulfur from the
coal. In the present article, study was carried out to investigate the
potential of biodesulfurization process in removing the sulfur from
lignite coal sample collected from a Mongolian coal mine. The batch
biodesulfurization experiments were conducted in 2.5 L borosilicate
baffle type reactors at 35 ºC using Acidithiobacillus ferrooxidans.
The effect of pulp density on efficiency of biodesulfurization was
investigated at different solids concentration (1-10%) of coal. The
results of the present study suggested that the rate of desulfurization
was retarded at higher coal pulp density. The optimum pulp density
found 5% at which about 48% of the total sulfur was removed from
the coal.
