ABSTRACT:
A process is disclosed for the fermentative preparation of amino acids, in which an L-lysine producing bacterial strain of the species Corynebacterium glutamicum is cultivated in a nutrient medium and the amino acids can be isolated from the culture medium 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 quanitity of other necessary supplements provided in the nutrient medium.
