Abstract

A process is disclosed for the fermentative preparation of amino acids, in which a strain of the genus Brevibacterium or Corynebacterium producing one or more amino acids is cultivated in a nutrient medium and the amino acids are isolated from the culture fluid at the end of fermentation. After the vigorous growth phase, the bacterial culture has at its disposal a smaller quantity of assimilable carbon source than it could metabolize on the basis of the structure of the strain and the quantity of other necessary supplements provided in the nutrient medium.
