Abstract: The invention relates to a method for production of at least one non-volatile microbial metabolism product in solid form by sugar-based microbial fermentation, wherein a microbial strain producing the required metabolism product is cultivated with a sugary liquid medium with a monosaccharide content of more than 20 wt. %, based on the total weight of the liquid medium, the volatile components of the fermentation brew are mostly removed, the sugary liquid medium being produced by: a1) milling a starch source selected from cereal grains, a2) liquefying the milled material in an aqueous liquid in the presence of at least one starch-digesting enzyme and subsequent saccharification using at least one saccharifying enzyme, wherein the liquefying is carried out with addition of a partial amount of the milled material to the aqueous fluid continuously or batch-wise. The invention further relates to a solid formulation obtained by the above method of a non-volatile microbial metabolism product and the use of such a solid formulation as additive or supplement to animal or human food or for textile, leather, cellulose, paper or surface treatments.

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. Furthermore, the invention relates to a solid formulation, of a nonvolatile microbial metabolite, obtainable by the method according to the invention; and to the use of such a solid formulation as additive or supplement for human or animal nutrition or for the treatment of textiles, leather, cellulose, paper or surfaces.
