对嗜热古细菌Acidianus brierleyi在黄铁矿氧化过程中的作用进行了研究。微生物的生长都通过膜与黄铁矿分离，并与黄铁矿紧密接触。从结果可以得出结论，直接接触是需要良好的增长的菌株研究。结果表明，直接接触机理可应用于A。brierleyi。
Experiments were done in order to study the thermophilic archaebacterium Acidianus brierleyi during oxidation of pyrite (FeS2). The microorganisms were grown both separated from the pyrite by a membrane and in close contact with the pyrite. From the results it can be concluded that direct contact is needed for good growth of the strain studied. The obtained results indicate that the direct contact mechanism may be applied to oxidation of sulfidic minerals by A. brierleyi.
