The acid main drainage (AMD) in Dabaoshan mine is of extreme low pH values (pH=2.5~3.5) and high concentrations of ions such as Cd

which causes serious pollution of its downstream ecology. A strain of
Acidithiobacillus ferrooxidans
was isolated from the AMD and its growth properties were preliminarily studied. During the isolation of the strain
jarosite formed. The formation of jarosite results in the decrease of pH value of the solution. An experiment showed that concentrations of heavy metal ions such as Cd

in the AMD cultured with 9K media of pH 2.0~2.5 are higher than those with 9K medium of pH 3.0.
