Title (EN) PROCESS FOR THE FERMENTATIVE PREPARATION OF D-PANTOTHENIC ACID USING CORYNEFORM BACTERIA
(FR) PROCEDE DE PREPARATION PAR FERMENTATION D'ACIDE D-PANTOTHENIQUE AU MOYEN DE BACTERIES DE TYPE CORYNEBACTERIE
Abstract: front page image
(EN)The invention relates to a process for the preparation of D-pantothenic acid by fermentation of coryneform bacteria, in which bacteria in which the nucleotide sequence which codes for pyruvate oxidase (EC 1.2.2.2) (poxB gene) is attenuated are employed, the following steps being carried out: a) fermentation of D-pantothenic acid-producing bacteria in which at least the gene which codes for pyruvate oxidase is attenuated. b) concentration of the D-pantothenic acid in the medium or in the cells of the bacteria; and c) isolation of the D-pantothenic acid produced.
(FR)L'invention concerne un procédé de préparation d'acide D-pantothénique par fermentation de bactéries de type corynebactérie, dans lequel on utilise des bactéries contenant une séquence nucléotidique atténuée codant pour la pyruvate oxydase (EC 1.2.2.2) (gène poxB), le procédé consistant à a) faire fermenter des bactéries produisant l'acide D-pantothénique dans lesquelles le gène codant pour la pyruvate oxydase est atténué, b) à concentrer l'acide D-pantothénique dans le milieu ou dans les cellules de bactéries, et c) à isoler l'acide D-pantothénique produit.
