Title (EN) PROCESS FOR THE PREPARATION OF L-AMINO ACIDS USING STRAINS OF THE ENTEROBACTERIACEAE FAMILY WHICH CONTAIN AN ATTENUATED ACEB GENE
(FR) PROCEDE DE PREPARATION DE L-AMINO-ACIDES AU MOYEN DE SOUCHES DE LA FAMILLE ENTEROBACTERIACEAE CONTENANT UN GENE A CEB ATTENUE
Abstract: front page image
(EN)The invention relates to a process for the preparation of L-amino acids, in particular L-threonine, in which the following steps are carried out: a) fermentation of microorganisms of the Enterobacteriaceae family which produce the desired L-amino acid and in which the aceB gene, or the nucleotide sequence which codes for this, is attenuated, in particular eliminated, b) concentration of the L-amino acid in the medium or in the cells of the bacteria, and c) isolation of the L-amino acid.
(FR)L'invention concerne un procédé servant à préparer des L-amino-acides, en particulier, L-thréonine, ce qui consiste à exécuter les étapes suivantes: a) fermentation de micro-organismes de la famille Enterobacteriaceae produisant le L-amino-acide désiré et dans lesquels le gène aceB, ou la séquence de nucléotides codant pour ce gène, est atténué, en particulier, éliminé; b) concentration du L-amino-acide dans le milieu ou dans les cellules des bactéries; c) isolation du L-amino-acide.
