Title: NOVEL YEAST HAVING INCREASED CONTENT OF SULFUR-CONTAINING COMPOUND, SCREENING METHOD THEREOF, AND CULTURING METHOD THEREOF
Abstract:
A yeast having increased cellular content of sulfur-containing compounds such as γ-glutamylcysteine and glutathione can be obtained by combining selenic acid sensitivity and the property of red color development. The method to allow red color development includes imparting adenine-auxotrophy and culturing on a minimum medium supplemented with methionine.
