Study of Coal Microbiocenosis for Development of Biotechnological Method for its Desulfurization

Abstract

A presence of microscopic fungi, heterotrophic bacteria, as well as neutrophilic and acidophilic chemolitotrophic bacteria was determined in coal microbiocenosis. The largest and most active towards pyrite sulfur removal is the Acidithiobacillus genus. Heterotrophic bacteria have the biggest potential when it comes to removal of organic sulfur. Preceding treatment of coal with “silicate” bacteria from the Bacillus genus will allow to use coal microbiocenosis for its biodesulfurisation at its full potential.
