Acidophilic bacteria of the genera Thiobacillus and Sulfolobus are able to reduce ferric iron when growing on elemental sulfur as an energy source. It has been previously thought that ferric iron serves as a nonbiological oxidant in the formation of acid mine drainage and in the leaching of ores, but these results suggest that bacterial catalysis may play a significant role in the reactivity of ferric iron.
硫杆菌属和硫化叶菌属的嗜酸细菌在以元素硫作为能源生长时能够还原三价铁。以前人们认为三价铁在酸性矿山排水的形成和矿石浸出过程中作为一种非生物氧化剂,但这些结果表明细菌催化可能在三价铁的反应性中起重要作用。
