High-level production of the agmatine in engineered Corynebacterium crenatum with the inhibition-releasing arginine decarboxylase.

The engineered C. crenatum strain AGM3 in this work was proved as an efficient microbial cell factory for the industrial fermentative production of agmatine. Based on the insights from this work, further producing other valuable biochemicals derived from L-arginine by Corynebacterium crenatum is feasible.
