The aim of this paper was the evaluation of usefulness of bacterial leaching applied to a coal sample from the locality Nastup Tušimice. The results of this work proved that using clean cultures of Thiobacillus ferrooxidans was in this case very proper if we evaluated desulphurisation from the pyrite sulphur point of view. After one month of leaching, the pyrite sulphur was almost gone from the sample still containing a lot of organic sulphur amount of which decreased only slightly. The desulphurisation of pyritic sulphur reached about 71% while the total desulphurisation of coal - 42%.
