In the present work, the effects of different energy substrates and nickel ions (Ni2+) and cadmium ions (Cd2+) on the growth of Acidithiobacillus ferrooxidans (A. ferrooxidans) were investigated. Ferrous sulphate (FeSO4) was the optimum energy substrate for A. ferrooxidans growth, among the selected substrates. When cultured together with FeSO4 and sulphur (S), A. ferrooxidans first oxidised the ferrous ions (Fe2+), and the S was utilised as the concentration of Fe2+ decreased. After adapting to culture with Ni2+ and Cd2+, A. ferrooxidans presented good tolerance to both ions, with the maximum concentration reaching 4.11 g/L Ni2+ and 1.69 g/L Cd2+. A preliminary simulation of industrial application was also performed on used Ni-Cd batteries. With bioleaching, the highest concentrations of Cd2+ and Ni2+ were 3003 mg/L at day 8 and 1863 mg/L at day 14, respectively.

不同能量底物和镍，镉离子对酸性氧化铁硫杆菌生长的影响及其在处理镍镉电池中的应用。

在目前的工作中，研究了不同的能量底物和镍离子（Ni2 +）和镉离子（Cd2 +）对酸性硫代氧化亚铁细菌（A. ferrooxidans）生长的影响。在选定的底物中，硫酸亚铁（FeSO4）是A. ferrooxidans生长的最佳能量底物。当与FeSO4和硫（S）一起培养时，A。ferrooxidans首先氧化亚铁离子（Fe2 +），并且随着Fe2 +浓度的降低而利用S。适应Ni2 +和Cd2 +的培养后，A。ferrooxidans对两种离子都表现出良好的耐受性，最大浓度分别为4.11 g / L Ni2 +和1.69 g / L Cd2 +。还对用过的Ni-Cd电池进行了工业应用的初步模拟。随着生物浸出，
