嗜酸氧化亚铁硫杆菌的耐Mg^(2+)驯化试验研究

Experimental Investigation on Mg^(2+)-Resistant Domestication of Acidithiobacillus Ferrooxidans

考察了嗜酸氧化亚铁硫杆菌(A.t)对Mg2+的耐受能力,进行了细菌耐Mg2+驯化试验。结果表明,通过驯化,细菌对Mg2+的耐受能力大幅度增强,可用于高MgO含量的硫化镍矿的细菌浸出。

Mg^2＋-resistant capability of acidithiobacillus ferrooxidans （A. t） was investigated. Mg^2＋- resistant domestication tests of the bacteria were carried out to study Mg^2＋-resistant capability. The results show that Mg^2＋-resistant capability of the bacteria can be enhanced substantially. And the bacteria can be used to bioleaching of MgO-bearing low-grade nickel sulphide ore.
