摘　　要：构建了一种用于菌体培养-矿物浸取的气升式反应器. 分别采用Leathen和9K培养基研究了不同条件下氧化亚铁硫杆菌在气升式反应器中的生长、Fe2+氧化速率、溶氧随培养时间的变化及其相互关系. 通过测定溶氧和Fe2+氧化速率可了解培养条件对微生物生长特性的影响.Based on the growth characteristics of Thiobacillus ferrooxidans in bioleaching systems, an airlift reactor was constructed to cultivate the bacteria. Leathen medium and 9K medium under different conditions were used to study the growth of Thiobacillus ferrooxidans, Fe2+ oxidation rate, dissolved oxygen and their relationship in the airlift reactor. The influence of cultivation conditions on the growth of the bacteria was investigated by monitoring dissolved oxygen and Fe2+ oxidation rate.
