Definitions
- the present invention relates to a corynebacterium used for fermentative production of L-amino acids and the like represented by L-glutamic acid and L-lysine. Breeding and utilization of genus bacteria. 2. Description of the Related Art When Corynebacterium bacteria are cultured in a medium with a limited amount of biotin, the bacteria produce significant amounts of L-glutamic acid. On the other hand, when a Corynebacterium bacterium is cultured in a medium containing excess biotin, the bacterium does not produce L-glutamic acid. It is known that growth is suppressed and the bacterium produces significant amounts of L-glutamic acid.
- any of the following means is effective for producing L-glutamic acid using Corynebacterium bacteria.
- L-glutamic acid by the addition of a surfactant or benicillin has also been considered in connection with a change in permeability of the cytoplasmic membrane due to a change in the structure of the cell surface (I. Shiio, S. Otsuka, N. Katsuya: J. Biochem., 53, 333-340 (1963)).
- the object of the present invention is to provide a mechanism for the production of L-glutamic acid possessed by a bacterium belonging to the genus Corynebacterium, more specifically, the surface activity of a bacterium belonging to the genus Corynebacterium, which possesses a mechanism for producing L-glutamic acid.
- the purpose is to elucidate the mechanism of action of the additive and to breed and improve L-glutamic acid-producing bacteria belonging to the genus Corynebacterium based on the knowledge obtained.o
- a specific object of the present invention is to elucidate the L-glutamic acid production mechanism of Corynebacterium bacteria at the gene level, and isolate a gene involved in surfactant resistance derived from Corynebacterium bacteria, The purpose is to apply the obtained gene to breeding of L-glutamic acid-producing bacteria belonging to the genus Corynebacterium and to production of L-glutamic acid and the like.

- 50 GZm comprises one Orein acid M- CM 2 G and cultured in Plate medium was refreshed, the same strain was refreshed, glucose 80 g, KH 2 PO 4 lg , Mg S0 4 0. 4 g , (NH 4) 2 S0 4 30 g, F e S 04 7 H 2 0 0. 0 1 g, Mn SO 4 7 H 2 0 0.
- the wild-type strain and AJ11060 strain did not accumulate L-glutamic acid due to the presence of excessive amount of biotin in the medium, whereas the ⁇ ⁇ strain favored L-glutamic acid. Generated and accumulated.
- INDUSTRIAL APPLICABILITY The dtsR gene of the present invention is a gene having an important function in the production of L-glutamic acid in Corynebacterium bacteria used for fermentative production of L-glutamic acid, and has an L-lysine-producing ability. The ability to produce L-lysine can be improved by amplifying the same gene in Corynebacterium bacteria. In addition, in a bacterium belonging to the genus Corynebacterium having a glutamic acid-producing ability, the glutamic acid-producing ability can be improved by disrupting the gene.
