Reprogramming the sulfur recycling network to improve <scp>l</scp>-cysteine production in <i>Corynebacterium glutamicum</i>

Abstract

A bifunctional H 2 S 2 -responsive genetic circuit was established to realize sulfur recycling in Corynebacterium glutamicum , and the production of l -cysteine and the SCR were significantly increased by using this system.
