[Effect of cell reserve carbohydrates on an increase in the keeping qualities of baker's yeast].

Synthesis of reserve carbohydrates (trehalose and metabolically active glycogen) can be intensified in the cells of Saccharomyces cerevisiae by adding glycerol and magnesium or phosphorus salts to the cultural broth. An increase in the content of reserve carbohydrates in the cells increases their preservation after separation from the substrate.
