Abstract

The present invention relates to a process for the production of 2-KGA from L-sorbose by a continuous or semi-continuous fermentation mode, wherein a mixed culture of Gluconobacter oxydans DSM 4025 with a second microorganism component is used, or wherein, instead of the second microorganism component, the fermentation medium is supplemented with yeast or a yeast product.
