This study, investigated the ability of the soil yeasts Geotrichum candidum and Geotrichum capitatum to produce extracellular amylase in Czapek-Dox liquid medium amended with different concentrations of Cd, Co, Ca, Mrl, Ni ann Pb. Yeasts were able to survive ann grow in the medium containing up to 400 mu g/ml of metal ions. Addition of heavy metals caused a highly significant inhibition of amylase production by, soil yeasts tested. The amylolytic activity of G. candidum and G. capitatum decreased as the concentration of heavy metals increased: The soil yeast G. candidum exhibited the highest amylolytic activity.
