Title (EN) PROCESS FOR PRODUCING L-AMINO ACID
(FR) PROCEDE DE PRODUCTION D'ACIDE L-AMINE
Abstract:
(EN) A process for producing an L-amino acid (L-lysine, L-glutamic acid, etc.) by a fermentation method having been improved compared with the conventional methods which comprises transferring a gene encoding glucose 6-phosphate isomerase into a coryneform bacterium capable of producing an L-amino acid (L-lysine, L-glutamic acid, etc.) so as to potentiate the glucose 6-phosphate isomerase activity, thereby improving the L-amino acid productivity.
(FR) L'invention porte sur un procédé de production d'un acide L-aminé (L-lysine, acide L-glutamique, etc.) par un procédé de fermentation amélioré comparé aux procédés traditionnels. Ce procédé de fermentation amélioré consiste à transférer un gène codant glucose 6-phosphate isomérase dans un corynebacterium capable de produire un acide L-aminé (L-lysine, acide L-glutamique, etc.) de façon à potentialiser l'activité de glucose 6-phosphate isomérase, ce qui permet d'améliorer la productivité de l'acide L-aminé.
