    摘要： Highly concentrated aqueous L-Tryptophan and/or L-Threonine salt solutions are used to supplement mixed feeds with L-Tryptophan and/or L-Threonine. They can be metered easily and accurately, can be produced in a highly concentrated form with a content of between 30 and 70% and are storage stable to a surprisingly high degree (slight tendency to crystallize, no chemical decomposition, no racemization) even over a relatively long period of at least three months when outside temperatures are low.

    摘要： 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.

    摘要： 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.
