The present invention relates to a process for the production of sugar-based microbial fermentation of at least one microbial metabolite having at least 3 carbon atoms, or at least 2 carbon atoms and at least one nitrogen atom. The method of the invention comprises the following steps: a) producing a sugar-containing liquid medium having a monosaccharide content higher than 20% by weight from a starch source, wherein the sugar-containing liquid medium is also non-starch of the starch source B) fermenting a sugar-containing liquid medium to produce a metabolite; c) separating or isolating at least one metabolite from the fermentation broth, wherein the object is The microbial strain producing the metabolite of is cultivated in a sugar-containing liquid medium, which is: a1) milling the starch source, a2) the millbase in aqueous liquid, the presence of at least one starch liquefaction enzyme And then saccharifying the resulting liquid with at least one saccharifying enzyme, wherein at least part of the millbase is added continuously or discontinuously to the aqueous liquid Is liquefied. |
