Notes:
Acidithiobacillus ferrooxidans is used in bioleaching industrial operations to recovermetal ions from mineral sulfides. Chalcopyrite and bornite are copper sulfides that have the sameelemental composition, but differ in their susceptibility to the bioleaching process. Our objectivewas to identify differentially expressed proteins in A. ferrooxidans LR cells exposed to chalcopyriteor bornite, as a sole energy source, for 24 hours. Compared to the control (without minerals),proteins were induced or repressed in planktonic cells after contact with chalcopyrite or bornite by24 hours. These results demonstrated that the time of exposure to the copper minerals was enoughto trigger distinct responses in the A. ferrooxidans metabolism
