摘要
研究了氧化亚铁硫杆菌在９Ｋ培养基中生长及铁的行为．以Ｆｅ２＋的氧化表征氧化亚铁硫杆菌的生长特性及其活性，表明生长繁殖过程经历诱导期、缓慢期、指数期、稳定期和衰亡期．氧化亚铁硫杆菌在生长繁殖过程中，不断地将Ｆｅ２＋氧化为Ｆｅ３＋，同时Ｆｅ３＋又发生一系列的水解反应，并生成黄铵铁矾沉淀．Ｆｅ２＋的细菌氧化主要以Ｏ２为最终的电子受体．
おhe iron behaviour in growth of thiobacillus ferrooxidans in 9K medium has been investigated. The growth characteristic and activity of thiobacillus ferrooxidans can be expressed by the oxidation of Fe2+ in inoculum. It is indicated that the growth and breed of thiobacillus ferrooxidans pass through inductive period, lag period, exponential period, stationary period and death period. In these processes Fe2+ in solution are gradually oxidized to Fe3+, together with a series of hydrolytic reactions, a part of Fe3+ forms jarositetype precipitate. O2 is the ultimate electron recipient during the oxidation of Fe2+.
