Abstract
This invention is intended to improve glutathione productivity by fermentation using microorganisms. This invention relates to a microbial strain capable of overexpression of γ-glutamylcysteine, bis-γ-glutamylcystine, γ-glutamylcystine, reduced glutathione, and/or oxidized glutathione in which the expression level of a gene encoding serine-O-acetyltransferase (EC:2.3.1.30) is enhanced and a method involving the use of such microbial strain.
Claims8
