Method for producing gamma-glutamylcysteine

摘要

The yeast which has gamma -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 gamma -glutamylcysteine content in its cells, whereby the yeast in which gamma -glutamylcysteine is accumulated is obtained.
