    Abstract

    When Saccharomyces cerevisiae was cultured in the presence of thorium, the element was accumulated by the cells and was visible in electron micrographs as electron dense granules. When thorium was present during exponential growth, these granules were located mainly in the vacuole, with some present in the cytosol. Where thorium was present only during the stationary phase, there appeared to be greater thorium deposition in the cell wall than during exponential growth and some vacuolar deposits were also evident. Thorium uptake by exponential-phase cells was not stimulated by glucose and was thus independent of metabolic energy.
