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:

Fermentative production of fine chemicals

The present invention relates to a method for manufacturing an aqueous glucose solution from the starch components of Triticeae grains, for example from rye, triticale or in particular wheat grains. The invention also relates to a glucose-based fermentation method for manufacturing organic compounds in which the glucose manufactured for fermentation is produced from the starch components of Triticeae grains by way of a method according to the invention.

Method for manufacturing an aqueous glucose solution from plants of the Triticeae species

A process for the fermentative production of at least one organic compound having at least 3 C atoms or having at least 2 C atoms and at least one 1 N atom, comprising the following steps:

Fermentative production of organic compounds

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 vapor into the suspension, in order to obtain temperatures greater than the pasting temperature of the starch obtained in the grinding materials.

Process for the production of at least one organic compound having at least 3 C atoms or having at least 2 C atoms and at least 1 N atom by fermentation. In particular, the process comprises milling a starch feedstock, thus obtaining a millbase which comprises at least part of the nonstarchy solid constituents of the starch feedstock; suspending the millbase in an aqueous liquid and liquefying the millbase present in the aqueous liquid in the presence of at least one starch-liquefying enzyme, obtaining an aqueous dextrin-containing medium (1) which comprises at least a part of the nonstarchy solid constituents of the starch feedstock; and using the aqueous dextrin-containing medium (1) in a fermentation for culturing a microorganism which is capable of overproducing the organic compound; wherein enzymes which hydrolyze the dextrins to monosaccharides are being added in an amount of less than 0.001% by weight based on the total weight of the starch feedstock employed, or not at all.

Fermentative production of organic compounds using substances containing dextrin

The present invention relates to a process for the production of an aqueous glucose solution from maize or maize kernels. The invention also relates to a glucose solution obtainable by this process, and to its use for the production of organic compounds. The process according to the invention comprises: a) fractionating dry milling of maize kernels, where the maize kernels are separated into a maize-starch-comprising endosperm fraction and a high-oil germ fraction and, if appropriate, a bran fraction; b) enzymatic liquefaction and saccharification of the maize starch in an aqueous suspension of the endosperm fraction, which gives an aqueous glucose solution comprising maize gluten; and c) depletion of the maize gluten and, if appropriate, any bran present from the aqueous glucose solution.

Method for the production of an aqueous glucose solution

The present invention relates to a process for producing methionine by fermentation, a process for isolating the methionine formed, the methionine-containing biomass produced in isolation, use thereof for producing a feedstuff or feed supplement, and also to the use of the isolated methionine for producing foodstuffs or feedstuffs or food supplements or feed supplements.
