    Abstract: The invention relates to a process for the fermentative production of amino acids, in which a strain of the genera Brevibacterium or Corynebacterium producing one or more amino acids is cultured in a nutrient medium and, at the end of the fermentation, the amino acid(s) is/are isolated from the culture fluid, which process is characterised in that following the strong growth phase the bacterial culture has less assimilable carbon source available than it could metabolise on account of the strain construction and of the amount of the otherwise necessary supplements provided in the nutrient medium.

    Abstract: Animal feed additives based on fermentation broth contain other fermentation broth ingredients in addition to the additive. After spray drying, such products generally have an inadequate apparent density and/or are tacky. Accordingly, auxiliaries such as for example, perlite or sawdust are added for pelletizing of the products. Alternatively, the products are freed from water by azeotropic distillation with paraffin oil to form pellets. The problem addressed by the invention was to provide a highly concentrated animal feed additive which, in particular, was to have an apparent density of at least 550 kg/m3 and a standardizable active-substance content. Stable pellets can be produced by pelletizing from a fermentation broth containing an animal feed additive when at least 33% by weight of the fermentation products are present. The pellets can be produced particularly effectively by pelletizing providing they are built up from at least 30% by weight of fine particles of which at least 70% by weight are smaller than 100 .mu.m in size. The biomass may be completely present, partly present or not present at all in the pellets. Animal feed additives, such as lysine, threonine or tryptophane, all containing fermentation broth products.

    Abstract: 2. Animal feed additives based on fermentation broth further contain, in addition to the additive, other fermentation broth constituents. Such products, after spray-drying, generally have an excessively low bulk density and/or are sticky. To granulate these products, processing aids have therefore been added, e.g. perlite or sawdust. Alternatively, such products have been dewatered by azeotropic distillation with paraffin oil to give granules. The object of the invention is a highly concentrated animal feed additive which, in particular, is to have a bulk density of at least 550 kg/m and a standardisable active compound content. 2.2. By pelletising, stable granules can be produced from an animal feed additive-containing fermentation broth if the fermentation product is contained at at least 33% by weight. Granules can particularly readily be produced by pelletising if the pellets are built up of at least 30% by weight fine grain with at least 70% by weight having a particle size

    Abstract: 2.1. Fermentative preparation of amino acids for animal feed supplement purposes is a complex process, since the amino acid is present in the fermentation broth at only a few percent. Drying the crude fermentation broth and using it as such generally led to aggregating sticky products or to products having too low a supplementary amino acid content. Using the new animal feed supplement and preparation process, a supplementary amino acid is intended to be made available which is not too expensive, not excessively hygroscopic or sticky, and whose contents can be standardised. 2.2. The animal feed supplement is based on a fermentation broth and contains the majority of its components, if required, with the exception of part of the biomass. Preferably, the biomass is present at no more than 10 % by weight of the dry matter. Proteins are preferably present at up to a maximum of 10 % by weight. For the production, during fermentation, at least towards the end, the sugar content is adjusted to a value of at most 4 g/l and during further processing, if required, at least a part of the biomass is separated off. 2.3. Supplementation or preparation of animal feed agents or premixes, in particular containing lysine.

    Abstract: The gaseous mixture resulting from the catalytic reaction of 3-methylpyridine with ammonia and oxygen is treated with water to recover 3-cyanopyridine. The treatment takes place in two steps. In the first step there is used a temperature of about 30 DEG to 60 DEG C. and in the second step at a temperature about 10 DEG to 30 DEG C. lower than in the first step.
