Bioelimination of sulfur from high-sulfur coal by selected strains of microorganisms

Bioelimination of sulfur from high-sulfur coal by selected strains of microorganisms

In this study, low-rank lignite coal sample collected from Lenger coal deposit (Turkestan province) in Kazakhstan was subjected to desulfurization by using three bacterial strains isolated from soil with silt and coal itself. The molecular identification of the 16S rRNA gene revealed that the isolat...
