Abstract

The present disclosure relates to a microorganism producing L-leucine and a method for producing L-leucine using the same, and more specifically, to a Corynebacterium glutamicum mutant which has resistance to L-leucine and a derivative thereof and improved L-leucine producing ability, and a method for producing L-leucine using the same.

Claims (7)

1. A Corynebacterium glutamicum mutant that produces L-leucine selected from the group consisting of a mutant deposited under Accession No. KCCM11661P and a mutant deposited under Accession No. KCCM11662P.

2. The Corynebacterium glutamicum mutant of claim 1 , wherein the mutant has resistance to L-leucine and a derivative thereof,

and wherein the derivative is selected from the group consisting of leucine, isoleucine, terleucine, norleucine, and cycloleucine.

3. The Corynebacterium glutamicum mutant of claim 2 , wherein the L-leucine derivative is norleucine (NL).

4. A method for producing L-leucine, comprising:

culturing the Corynebacterium glutamicum mutant of claim 1 ; and

recovering L-leucine from the Corynebacterium glutamicum mutant or the culture.
