  • Publication number: 20090226571
    Abstract: The present invention relates to a method for the production of at least one nonvolatile microbial metabolite in solid form by sugar-based microbial fermentation, in which process a microorganism strain which produces the desired metabolites is grown using a sugar-containing liquid medium with a monosaccharide content of more than 20% by weight based on the total weight of the liquid medium, and the volatile constituents of the fermentation liquor are subsequently largely removed, the sugar-containing liquid medium being prepared by: a1) milling selected starch feedstock from cereal grains; and a2) liquefying the millbase in an aqueous liquid in the presence of at least one starch-liquefying enzyme, followed by saccharification using at least one saccharifying enzyme, where, for liquefaction purposes, at least a portion of the millbase is liquefied by continuous or batchwise addition to the aqueous liquid.
