Abstract
The present invention relates to a recombinant microorganism capable of producing putrescine at high yield due to inactivated activity of a protein having an amino acid sequence represented by SEQ ID NO: 2 in the microorganism, and a method of producing putrescine using the microorganism.
Claims8
An isolated microorganism of genus Corynebacterium having putrescine productivity, wherein a protein having an amino acid sequence represented by SEQ ID NO:
- 2 is inactivated.
A method of producing putrescine, comprising:
- culturing a microorganism of genus Corynebacterium having putrescine productivity wherein a protein having an amino acid sequence represented by SEQ ID NO:
- 2 is inactivated, in a culture medium;
- and
- separating putrescine from the cultured microorganism or the culture medium obtained from the above step.
