Coal desulfurization by leaching involving acidophilic and thermophilic microorganisms [PDF]
Biotechnology and Bioengineering, 1982 It was shown that thermophilic microorganisms can increase the rate and volume of pyrite leaching from pulverized, high-sulfur coal. This occurs not only because of the elevated temperature of operation possible, but also the apparent accelerated catalytic activity of thermophilic microorganisms as compared to autotropic microbes such as T ...
