Abstract

A study was carried out to develop strains of Thiobacillus ferrooxidans ATCC 19859 tolerant to higher levels of heavy metal ions. Strains of T. ferrooxidans capable of growing in $Cu^{2+}$ (30 g/L) and $Zn^{2+}$ (60 g/L) have been obtained. The ability of strains tolerant to either copper or zinc to grow in medium containing both the metals has been examined. The copper-tolerant strain (25 g/L) grows better in the medium containing both metals ($Cu^{2+}$ 25 g/L and $Zn^{2+}$ 40 g/L) compared to the zinc-tolerant strain (40 g/L).
