一株嗜酸氧化亚铁硫杆菌的鉴定及浸矿性能

从西藏甲玛某多金属矿的酸性矿坑水中分离获得一株浸矿细菌（命名为XZ）．该菌为革兰氏阴性菌，短杆状，菌体长约1—1．5μm，直径约0．5μm，两端钝圆，能够氧化Fe2＋和单质硫，最适生长pH为2．0，最适生长温度为30℃，经过对其生长特性进行研究及16SrRNA基因测序鉴定其为一株嗜酸氧化亚铁硫杆菌．利用XZ菌对西藏某低品位铜矿角岩矿进行了摇瓶浸出试验研究，结果表明，在接种量体积分数为10％，矿浆质量分数为10％，矿石粒度为-45μm占100％，培养温度30℃，振荡强度160r／min的浸出条件下，经过15d，Cu2＋的浸出率达72．15％．...

A bioleaching bacterium was isolated from an acidic mine drainage of Jiama polymetallic mine in Tibet and was named as XZ. The strain XZ, with round ends, is gram- negative and short-rod shaped in 1 - 1.5 μm × 0. 5 μm. Ferrous iron and elemental sulfur could be oxidized by strain XZ. The optimum growth pH is 2.0 and the optimum growth temperature is 30℃, It was identified as Acidithiobacillus ferrooxidans by means of growth characteristic research and 16 S rRNA sequencing. The strain XZ was used to leach a poor copper hornstone ore took from Tibet. Shaking flask leaching tests were carded out with
