Stability of the Plasma Membrane in Saccharomyces rouxii and Its Relationship to Glucose Tolerance

Abstract

The stability of spheroplasts from the osmotrophic yeast Saccharomyces rouxii was studied in buffered solutions of mannitol and glucose. The plasma membranes from cells grown in high glucose concentrations were more stable to osmotic lysis than were membranes from cells grown in lower glucose concentrations. Mannitol was a better osmotic stabilizer than glucose, except when the cells were grown in a high glucose concentration. Spheroplasts from a glucose tolerant-deficient mutant were much less stable than the corresponding spheroplasts from the parent strain, especially when suspended in glucose solutions. These results suggest an involvement of the plasma membrane in the glucose-tolerant mechanism of S. rouxii.
