Abstract
SUMMARY: Saccharomyces cerevisiae can accommodate to the presence of toxic levels of Cd2+. This adaptation can also be induced, though to a lesser degree, by pre-growth of the yeast in 50 µM-Zn2+. Growth of Cd2+-adapted yeast through several passages in Cd2+-free medium leads to a progressive decrease in Cd2+-tolerance by the yeast, suggesting that the adaptation did not involve selection of a Cd2+-resistant mutant. Chromatography on Sephadex G-75 of the soluble fraction from Cd2+-adapted yeast indicated that no metallothionein-like protein was present. This suggests that the mechanism of adaptation is unlike that of the higher eukaryotes.This publication has 3 references indexed in Scilit:
