[Effect of saccharose and lactose on the resistance of Saccharomyces cerevisiae yeast to desiccation].

Incubation of Saccharomyces cerevisiae cells in solutions containing different sucrose or lactose concentrations (0.25 to 1.0 M) makes the organism more resistant to dehydration. The effect is increased when the cells are incubated for longer periods of time. Apparently, certain intracellular reactions making the yeast survive upon dehydration are initiated under these conditions.
