Title (EN) PROCESS FOR THE PREPARATION OF L−AMINO ACIDS USING STRAINS OF THE FAMILY ENTEROBACTERIACEAE
(FR) PROCEDE DE PREPARATION DE L-AMINOACIDES AU MOYEN DE SOUCHES DE LA FAMILLE DES ENTEROBACTERIACEES
Abstract: front page image
(EN)The invention relates to a process for the preparation of L−amino acids, especially L−threonine, in which the following steps are carried out: a) fermentation of microorganisms of the family Enterobacteriaceae which produce the desired L−amino acid and in which the pepB gene, or nucleotide sequences coding therefor, is (are) enhanced and, in particular, overexpressed, b) enrichment of the desired L−amino acid in the medium or in the cells of the bacteria, and c) isolation of the desired L−amino acid.
(FR)L'invention concerne un procédé de préparation de L-aminoacides, et notamment de L-thréonine. Ce procédé consiste (a) à fermenter des micro-organismes de la famille des entérobactériacées qui produisent le L-aminoacide souhaité, et dans lesquels le gène pepB, ou les séquences nucléotidiques codant pour celui-ci, est stimulé, et plus particulièrement surexprimé, (b) à enrichir le L-aminoacide souhaité dans le milieu ou dans les cellules de la bactérie, et (c) à isoler le L-aminoacide souhaité.
