Effects of copper and cadmium on growth, superoxide dismutase and catalase activities in different yeast strains.

Author information

Department of Biology, University of Padova, Italy.


1. Three strains of Saccharomyces cerevisiae have been adapted in vitro upon treatment with copper or cadmium. Growth rate, cellular size, metal uptake, superoxide dismutase and catalase activities were measured. 2. Growth rate and metal uptake are quite different among the yeast strains and also for copper and cadmium treatment. At the employed concentrations, only cadmium chiefly affects the cellular volume. 3. Cu, ZnSOD activity is stimulated in the presence of copper, while it is lightly inhibited in the presence of cadmium. Catalase level remains almost unchanged in the conditions tested. This lack of correlation is then discussed.
