[Effect of glutamic acid on Saccharomyces cerevisiae cell permeability during rehydration after dehydration].
Losses of potassium ions, nucleotides and protein substances were studied upon rehydration of Saccharomyces cerevisiae cells grown on a defined nutrient medium with ethanol and glutamic acid (0.075%) and subjected to dehydration. Considerable amounts of K+ (75--82% of the total), nucleotides and protein substances were found to be released into distilled water upon rehydration of the dehydrated yeast cells. If a higher percentage of yeast cells survived, these lost less nucleotides and nitrogen-containing substances. Glutamic acid being added to the growth medium did not decrease specifically the permeability of the dehydrated yeast cells upon rehydration.
