ABSTRACT: Thiobacillus ferrooxidans treated with ethylmethane sulfonate and UV rays was incubated with coal sample taken from Assam, India for its desulfurization capacity. 2% glucose and 0.7% NH4Cl served as the best carbon and nitrogen sources respectively. Optimum concentration of both MgCl2 and KH2PO4 in fermentation medium was 0.025% supplementation of medium with 10 µg/ml Fe2(SO4)3.H2O had marked positive effect on desulfurization. Optimization of chemical nutrients resulted in a significant (p<0.05) impact on desulfurization (66.1%) by the mutant strain Thiobacillus ferrooxidans X200 as against parent strain (55.1%).
