"CEPA DE SACCHAROMYCES CEREVISIAE, YEAST EXTRACT PRODUCED BY CULTIVATING A CEPA OF SACCHAROMYCES CEREVISIAE, AND, PROCESS FOR THE REPRODUCTION OF A CEPA OF SACCHAROMYCES CEREVISIAE CONTAINING EPSILON-GLAMILY-GLAMILY." Yeast extract is produced using a strain of Saccharomyces cerevisiae, which can contain 1% or more of y-glutamylcysteine and contains 0.004-0, 1% by weight of glutathione during its logarithmic growth phase, when the strain is grown in a medium in which a strain of Saccharomyces cerevisiae deficient in glutathione synthetase has a lower growth rate than a wild type strain, for example, a strain of Saccharomyces cerevisiae, in which glutathione synthetase encoded by a glutathione synthetase gene a chromosome has a deletion of a C-terminal region starting from the 370 198 arginine residue. yeast is provided that can be used for industrial production and has a high amount of accumulation of y-glutamylcysteine and yeast extract produced by the use of yeast.
