Abstract
The present invention relates to a novel isolated gene (polynucleotide) which encodes a protein having a biofilm formation inhibitory activity derived from Coryneform bacteria, a L-lysine-producing strain in which the polynucleotide is inactivated, and a method for producing L-lysine using the same.
Claims6
Corynebacterium glutamicum wherein a gene with a nucleotide sequence as set forth in SEQ ID NO:
- 1 is inactivated.
Corynebacterium glutamicum wherein a gene with a nucleotide sequence as set forth in SEQ ID NO:
- 2 is inactivated.
Corynebacterium glutamicum wherein genes with nucleotide sequences as set forth in SEQ ID NOs. 1 and 2 are inactivated.
A method for producing L-lysine comprising, culturing Corynebacterium glutamicum in a culture solution, in which a gene with a nucleotide sequence as set forth in SEQ ID NO:
- 1 is inactivated;
- and recovering lysine from the cultured bacteria or the culture solution thereof.
A method for producing L-lysine comprising, culturing Corynebacterium glutamicum in a culture solution, in which a gene with a nucleotide sequence as set forth in SEQ ID NO:
- 2 is inactivated;
- and recovering lysine from the cultured bacteria or the culture solution thereof.
A method for producing L-lysine comprising culturing Corynebacterium glutamicum in a culture solution, in which genes of nucleotide sequences as sey forth in SEQ ID NOS:
- 1 and 2 are inactivated;
