Biorcmoval of organic and inorganic sulfur in coal samples

摘要

The microbial ecology of different Spanish coal samples has been characterized by enrichment cultures at different growth conditions (1). From these studies several bacteria have been isolated and identified as members of the Xantomonas, Pseudomonas, Bacillus and Thiobacillus genus using their phenotypic and genotypic properties. Different isolates have been tested in desulfurization column experiments. The analysis of their capability for metabolizing organic as well as inorganic sulfur has shown their potential for industrial coal desulfurization processes.
