 note = {It was observed that about 90 % of Thiobacillus ferrooxidans in liquid was adsorbed on added activated carbon when the concentration of the cultivated bacteria reached about 5×10^9 cells m^{-3}. The oxidation of ferrous iron and the leaching of copper ore were carried out in shaking flasks, and in suspended bubbling columns. It was observed that the rates of oxidation and leaching increased when the microorganism was adsorbed on activated carbon. However, the evaluation of the reaction rates by eliminating the catalytic effect of activated carbon showed that the contribution to the reaction of the adsorbed microorganism was very small. As T. ferrooxidans gains the energy for metabolic activities by oxidizing ferrous iron into ferric iron, it is supposed that the adsorbed microorganism did not grow, and that its characteristics were changed by the interaction with the solids.},
