Abstract

L'invention concerne un procédé pour produire de l'acide ascorbique, selon lequel dans une première étape une source carbone est convertie par fermentation en acide 2,5-dicétone-D-gluconique, qui est ensuite mis en réaction de manière enzymatique avec une acide 2,5-dicétone-D-gluconique réductase provenant de Corynebacterium glutamicum pour produire de l'acide 2-céto-L-gluconique. L'objectif est d'améliorer le rendement. A cet effet, la source carbone est le glucose et la conversion du glucose en acide 2,5-dicéto-D-gluconique est directement produite par la souche Pectobacter cypripedii HEPO1 (DSMZ 12393).
