SUMMARY— When a strain of brewer's yeast grown under suitable conditions was suspended in a solution of fermentable sugar, nucleotides and other U.V.–absorbing materials were rapidly released from the cells. The extent of release was dependent on the pH of the medium, the temperature, the concentration of fermentable sugar and on the presence of membrane–protecting (Ca++ or Mg++) or membrane–damaging (butanol, detergent) reagents. The released material was of low molecular weight and appeared to originate in a free intracellular pool. It was concluded that the mechanism of release of nucleotidic material was the result of a change in permeability of the cytoplasmic membrane of yeast contingent upon the transport and metabolism of fermentable sugar. Leakage of nucleotidic material from yeast was considered to be a normal physiological process of consequence in the brewing and wine–making industries.
