High sulfur containing lignite was investigated for the removal of sulfur content by bacterial cultures using shake flask experiments. The effect of bacterial action on unwashed and washed lignites with dilute acid was tested and found that the lignite does not require any pretreatment prior to microbial desulfurization process. Results indicate that 78 percent removal of the total sulfur is possible by using 5 percent lignite slurry concentration within 18 days by mixed cultures of Thiobacillus ferrooxidans and Thiobacillus thiooxidans. The results also show improvement in lignite quality as volatile matter and ash content are reduced during microbial desulfurization. 13 refs., 2 figs., 2 tabs.
