Abstract
Acidophilic microorganisms were enriched from acid mine water samples and differentiated by their growth in liquid media containing either glucose or different inorganic compounds as electron donors. The choice of substrate for enrichment cultures determined the substrate utilization pattern on subsequent transitions. The solubilization of aluminum, cobalt, copper, iron, nickel and zinc from sulfide ore material was determined with three selected enrichment cultures. Relative differences with respect to the oxidation of sulfide minerals could be attributed to the previous growth history of the test cultures.
