[Distribution of trehalose between the cells and the rehydration medium in dehydrated Saccharomyces cerevisiae].

The work was concerned with studying the balance of trehalose distribution between the rehydration medium and Saccharomyces cerevisiae cells grown in a chemically defined medium and dehydrated using the convective technique. A direct linear correlation between the viability of populations and the overall residual trehalose content in the cells and in the medium after the rehydration of dry yeast cells was shown to be most important. An inverse correlation was established between the viability of yeast cells and the amount of trehalose mobilised by the cells in the process of rehydration.
