Abstract
The present invention relates to a new mutant strain induced from a wild strain of the genus Escherichia, which is active upon a .gamma.-glutamyl-L-cystein synthesizing enzyme system and capable of releasing .gamma.-glutamyl-L-cystein synthetase from inhibition by glutathione. It preferably is Escherichia coli RC 912 (FERM-BP No. 47). The present invention also contemplates the preparation of glutathione by (1) culturing the foregoing strain in a culture medium' or (2) culturing said strain to first accumulate a .gamma.-glutamyl-L-cystein synthesizing enzyme system, and placing the latter into contact with a substrate of L-glutamic acid, L-cysteine and glycerine to form gluthatione by enzymatic reaction.
