Abstract

A microorganism of the genus Corynebacterium with an improved ability to produce L-lysine in which a septum formation initiator protein is inactivated and a method for producing L-lysine using the microorganism.

First claim

The invention claimed is:

1. A Coryneform microorganism with an improved ability to produce L-lysine in which a septum formation initiator protein is inactivated, wherein the septum formation initiator protein is a filamentous temperature sensitive B (FtsB) protein.

2. The microorganism according to claim 1 , wherein the septum formation initiator protein has the amino acid sequence of SEQ ID NO: 1.

3. The microorganism according to claim 1 , wherein the Coryneform microorganism is Corynebacterium glutamicum.

4. A method for producing L-lysine, the method comprising:
culturing the microorganism of claim 1 , to produce L-lysine in a culture medium; and
recovering L-lysine from the microorganism or the culture medium.
