Abstract

Summary: Ca protected yeast ceJls very effectively against the toxic effects of Cd; Mghad only a slight protecting effect as far as protection against Cd-induced release of K was concerned. Protection of the yeast cells against Cd toxicity was due to a reduction in Cd uptake in the presence of Ca. A single relationship existed between the relative rate of K release induced by Cd and the cellular Cdconcentration. Within the first few minutes of incubating cells with Cd. the molar ratio of K released and Cd accumulated was 22 and was independent of the amount of CdC1 added. This ratio decreased during incubation of the cells with Cd. depending on the external Cdconcentration.
