摘要： Provided are mutant microorganisms having the ability to produce a high concentration of putrescine wherein gene(s) involved in the putrescine degradation or utilization pathway is inactivated or deleted and a preparation method thereof. A method for producing putrescine in high yield by culturing the mutant microorganisms is also provided. The mutant microorganisms are useful for producing a high concentration of putrescine which can be widely used in various industrial applications.
