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.
