    Abstract: Preparation of at least one organic compound (I) with at least 3 C atoms or at least two C and at least one N by fermentation. Preparation of at least one organic compound (I) with at least 3 C atoms or at least two C and at least one N by fermentation comprises: (a) millling a starch source (S) to form a milled product (MP) that contains at least part of the non-starch-containing solid components (X) of (S); (b) suspending (MP) in an aqueous liquid and hydrolysis of the starch components by enzymatic liquefaction and optionally subsequent saccharification, to form a first liquid medium (1), containing mono- or oligo-saccharides; and (c) adding (1), together with metabolizable mono-, di- and/or oligo-saccharides (Y), or compositions containing at least 50wt.% (Y) essentially free of water-insoluble solids, to a fermentation medium that contains microorganisms (MO) which can overproduce (I), under fermentation conditions.

    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.

    Abstract: A specific nucleic acid (I) with promoter activity is used for transcribing genes, where (I) is: (a) a sequence (1) of 178 nucleotides (reproduced); (b) a derivative of (1) with >= 90% identity, formed by substitution, insertion or deletion; (c) a sequence that hybridizes to (1) under stringent conditions; or (d) a functional fragment of (a)-(c). Independent claims are also included for: (1) use of an expression unit (EU), containing and linked to a nucleic acid (NA) that ensures translation of RNA, for expressing genes; (2) (I), except sequence (1) itself, as new compounds and EU containing it; (3) method for altering (or causing) the transcription (or expression) rate of genes in microorganisms relative to the wild type; (4) expression cassette (EC) comprising EU, at least one other functionally linked NA to be expressed and optionally other genetic control elements that are heterologous with respect to EU; (5) expression vector containing EC; (6) genetically modified microorganism (GMM) in which the transcription rate of at least one gene is altered (or caused) relative to the wild type; (7) GMM containing EU and a functionally linked gene to be expressed, where this is heterologous with respect to EU; (8) preparation of biosynthetic products (A) by culturing the GMM of (6) or (7); (9) use of the sequence aggagga (21) as ribosome-binding site in expression units for expressing genes in Corynebacterium or Brevibacterium; (10) use of the sequences ttaatt (19) or taagct (20) as -10 regions in EU for expressing genes in Corynebacterium or Brevibacterium; and (11) EU that contain (21) or at least one of (19) or (20).
