Summary Thiobacillus TH1 is an acidophilic chemolithotrophic heterotroph growing at temperatures up to about 50°C on media containing ferrous iron or pyrite when supplemented with yeast extract or glutathione. Virtually no carbon dioxide fixation occurred during growth on iron with yeast extract. Its DNA contains 48 mol % guanine + cytosine. The organism effects the thermophilic leaching of metals from pyrite, chalcopyrite, CuS, and copper concentrates. Oxidation of soluble ferrous iron at pH 1.6 was competitively inhibited by ferric iron and had a Km of 7.3 mM FeSO4.
