  • Mutants of with efficient expression of exogenous proteins and method of use thereof
    Patent number: 12163121
    Abstract: The present invention provides a mutant strain of Corynebacterium glutamicum with efficient expression of exogenous proteins, which can solve the technical problem of low protein expression quantity of using Corynebacterium glutamicum as an exogenous protein expression host. The mutant strain of Corynebacterium glutamicum is deposited in the China General Microbiological Culture Collection Center (CGMCC), and the deposit number is CGMCC No. 20138. The mutant strain of Corynebacterium glutamicum in the present invention, verified by the expression of exogenous proteins, shows a significantly enhanced expression of both intracellular and secreted proteins when compared with its initial strain.
