    Abstract: The invention relates to a process for the production of at least one microbial metabolite having at least 3 carbon atoms or at least 2 carbon atoms and at least 1 nitrogen atom by means of sugar-based microbial fermentation, comprising: a) the preparation of a sugar-containing liquid medium with a monosaccharide content of more than 20% by weight from a starch feedstock, the sugar-containing liquid medium also comprising non-starchy solid constituents of the starch feedstock; b) the fermentation of the sugar-containing liquid medium for the production of the metabolite(s); and c) depletion or isolation of at least one metabolite from the fermentation liquor, wherein a microorganism strain which produces the desired metabolite(s) is cultivated with the sugar-containing liquid medium, said liquid medium being obtained by: a1) milling the starch feedstock; 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 at least some of the millbase is liquefied by continuous or batchwise addition to the aqueous liquid.

    Abstract: The invention relates to a method for producing at least one organic compound comprising at least 3 C-atoms or at least 2 C-atoms and at least 1 N-atom by fermentation. Said method comprises the following steps: i) a starch source is ground in order to obtain a grinding material which contains at least one part of the non-starch containing solid components of the starch source; ii) the grinding material is suspended in an aqueous liquid in an amount such that the dry mass content in the suspension is at least 45 wt. %, iii) the starch component is hydrolysed in the grinding material by liquefying and optionally, subsequently, sweetening, in order to obtain an aqueous medium M, which contains the hydrolysed starch components and at least one part of the non- starch containing solid components of the starch source, is obtained; and iv) the aqueous substance M obtained in step iii) is used for fermentation in order to cultivate a micro-organism which is capable of over-producing the organic compound; the suspension obtained in step ii) is heated in step iii) by introducing vapour into the suspension, in order to obtain temperatures greater than the pasting temperature of the starch obtained in the grinding materials.

    IPC: C07H3/04

    Abstract: The invention relates to a process for enriching trehalose from solutions, in which the enrichment is performed using an adsorbent, in which the adsorbent is an aluminosilicate. Preferably, the aluminosilicate is a zeolite. The invention further relates to the enrichment and purification of trehalose from fermentation broths, in particular as a coupled product of production by fermentation of other products of value.
