[Effect of nitrogen and phosphorus in the medium on the level of reserve carbohydrates in the cells of a dividing baker's yeast culture].

Changes in the content of reserve carbohydrates (trehalose, glycogen) were studied in the cells of baker's yeast during their continuous cultivation at various doses of nitrogen and phosphorus in the medium. The content of reserve carbohydrates in the cells, and their viability, increased with a decrease of nitrogen in the medium. Phosphorus displayed the opposite effect, which was however insignificant within the range of its concentrations used in the experiments.
