Abstract

Abstract This investigation has demonstrated that the chalcopyrite oxidation ability of Thiobacillus ferrooxidans is considerably reduced in presence of the surface active agents, such as Tween 20, 40, 60 and 80. The bacterial activity, the surface tension of the medium and the oxygen concentration at saturation were inversely proportional to the concentration of the surface active agents studied.
