    • Abstract


      A study was carried out to develop strains ofThiobacillus ferrooxidans ATCC 19859 tolerant to higher levels of heavy metal ions. Strains ofT. ferrooxidans capable of growing in Cu2+ (30 g/L) and Zn2+ (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 (Cu2+ 25 g/L and Zn2+ 40 g/L) compared to the zinc-tolerant strain (40 g/L).
