Effects of Ion Stress on the Oxidation Activity of Acidithiobacillus ferrooxidans

Abstract:

The effects of stresses induced by four ions (potassium, magnesium, aluminum and fluoride ions) on the growth and activity of Acidthiobacillus ferrooxidans LD-1 (At.f LD-1) were investigated. The results showed that these four ions inhibited the growth and activity of At.f LD-1 to different extents. The inhibition effect of these four ion stresses followed the order potassium < magnesium < aluminum < fluoride. The inhibition effects of the trivalent metal ion (aluminum) are greater than divalent (magnesium) and monovalent (potassium) ions at the same concentrations. The inhibition of cations on At.f LD-1 was stronger than that of anions.
