Applicability of the manometric method for studying the oxidation of pyritic material in the presence of bacteria has been demonstrated. Resting cells of Ferrobacillus ferrooxidans accelerated the oxidation of coal pyrites and coarsely crystalline marcasite, but were inactive on coarsely crystalline pyrite. Resting cells of Thiobacillus thiooxidans were inactive on all pyrites tested. Oxidation rates in the presence of Ferrobacillus were increased by reducing the particle size of pyritic samples, and, in one case, by removing the CaCO(3) from a calcite-containing sample.
已证明测压法在研究细菌存在下黄铁矿材料氧化方面的适用性。氧化亚铁硫杆菌的静止细胞加速了煤黄铁矿和粗晶白铁矿的氧化，但对粗晶黄铁矿无活性。氧化硫硫杆菌的静止细胞对所有测试的黄铁矿均无活性。通过减小黄铁矿样品的粒度，以及在一种情况下通过从含方解石的样品中去除碳酸钙，可提高存在氧化亚铁硫杆菌时的氧化速率。
