Abstract Growth and iron oxidation by Thiobacillus ferrooxidans are affected by the presence of silver, molybdenum, uranium and copper. Growth is more sensitive to the presence of these metals than the iron oxidation system of the bacterium. Silver toxicity is much more specific than molybdenum and uranium.

It has been well established that Acidithiobacillus Thiobacillus ferrooxidans thrives on the mineral pyrite FeS 2. These bacteria oxidize pyritic sulfur to sulfuric acid and thus create an acidic environment according to the following scheme: S 2 + S 0 + 3.5 O 2 + H 2 O 2 H + + 2 SO 4 2 . Under acidic conditions, they also exploit the oxidation of ferrous iron according to: 4
