    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: 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.
