    Isolation and Characterization of Acidithiobacillus ferrooxidans Strain D3-2 Active in Copper Bioleaching from a Copper Mine in Chile

    SUGIO Tsuyoshi , WAKABAYASHI Masanori , KANAO Tadayoshi , TAKEUCHI Fumiaki

    … Acidithiobacillus ferrooxidans strain D3-2, which has a high copper bioleaching activity, was isolated from a low-grade sulfide ore dump in Chile. … Since sulfite ion is a highly toxic intermediate produced during sulfur oxidation that strongly inhibits iron oxidase activity, these results confirm that strain D3-2, with a unique sulfite resistant-sulfite oxidase, was able to solubilize more copper from chalcopyrite than strain ATCC 23270, with a sulfite-sensitive sulfite oxidase. …
