Abstract
The yeast which has γ-glutamylcysteine-producing ability and is auxotrophic for pantothenic acid is proliferated in a medium containing a sufficient amount of pantothenic acid, and then it is cultured in a medium containing a limited amount of pantothenic acid to increase the γ-glutamylcysteine content in its cells, whereby the yeast in which γ-glutamylcysteine is accumulated is obtained.
