FIELD: biotechnology.
SUBSTANCE: disclosed is a modified microorganism of the genus Corynebacterium producing putrescine with reduced activity of the sugar metabolism transcription (SugR) regulator compared to its endogenous activity and high activity of citrate synthase (GltA) compared to its endogenous activity. Disclosed is a method of producing putrescine using said microorganism.
EFFECT: group of inventions makes it possible to increase productivity of the specified modified microorganism by putrescine in comparison with non-modified microorganism.
