Abstract
The growth rate ofSaccharomyces cerevisiae was dependent on K+ content in culture medium in a certain range of K+ concentrations. Above the upper limit of the range, growth did not respond to K+ increase, and below the lower limit, yeast died. Rb+ and Na+ enhanced growth in the range of K+ dependence and decreased the K+ concentration below which cells died. Both Rb+ and Na+ became toxic above a certain Rb+/K+ and Na+/K+ cellular ratio.
