MUTANT MICROORGANISM HAVING HIGH ABILITY TO PRODUCE PUTRESCINE AND METHOD FOR PRODUCING PUTRESCINE USING THE SAME

摘要

The present invention relates to mutant microorganisms having high ability to produce putrescine in which genes involved in the putrescine degradation or utilization pathway of microorganisms having a putrescine-producing metabolic pathway are inactivated or deleted; and a method for producing putrescine in high yield by culturing the mutant microorganisms under anaerobic conditions. The mutant microorganisms having high ability to produce putrescine are useful for producing a high yield of putrescine which is used in a wide range of industrial applications.
