Three species of thermophilic archaebacteria of the genera Sulfolobus (Sulfolobus acidocaldarius and S. solfataricus) and Acidianus (Acidianus brierleyi) were tested for their ability to oxidize pyrite and to grow autotrophically on pyrite, to explore their potential for use in coal desulfurization. Only A. brierleyi was able to oxidize and grow autotrophically on pyrite. Jarosite was formed during the pyrite oxidation, resulting in the precipitation of sulfate and iron. The medium composition affected the extent of jarosite formation.
对硫化叶菌属（嗜酸硫化叶菌和嗜热栖热硫化叶菌）和嗜酸菌属（布氏嗜酸菌）的三种嗜热古细菌进行了测试，以考察它们氧化黄铁矿以及在黄铁矿上自养生长的能力，从而探索其在煤炭脱硫中的应用潜力。只有布氏嗜酸菌能够氧化黄铁矿并在其上自养生长。在黄铁矿氧化过程中形成了黄钾铁矾，导致硫酸盐和铁沉淀。培养基成分影响了黄钾铁矾的形成程度。
