摘要
从低品位黄铜矿浸矿菌液中分离到14株嗜酸、亚铁离子氧化菌株,并对菌株进行了Fe2+氧化率及其对低品位黄铜矿铜浸出率的测定。实验表明,YK12菌株的氧化活性最高,对该菌株进行系统进化分析表明,该菌株与分离自德国某废铀矿堆中的Acidithiobacillus ferrooxidans D2菌株(嗜酸氧化亚铁硫杆菌)相似性最高,可鉴定为嗜酸氧化亚铁硫杆菌菌株(Acidithiobacillus ferrooxidans)。
Fourteen acidophilic, ferrous ions oxidation strains were isolated from a low-grade chalcopyrite bioleaching culture, and the oxidation rate of Fe^2＋ and bioleaching rate of low-grade chalcopyrite were determined. The results show that strain YK12 has the highest oxidation activity. System phylogenetic analysis showed that strain YK12 is similar to strain Acidithiobacillus ferrooxidans D2 which was isolated from some waste uranium stockpile in Germany, and YK12 is identified as an Acidithiobacillus ferrooxidans strain.
