    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.

    摘要: A carrier strip of polyimide resin sheet material carries on one face an etched pattern of metallization comprising temperature-independent resistors formed of an underlying metallization layer of tantalum base, temperature-dependent resistors in which the effect of the upper layer of metallization, of a nickel base, is predominant, and conductive paths provided by broader strips of the nickel base material. A cover layer of the same heat-resistant resin sheet material is sealed and bonded to the carrier strip wherever a metallization layer does not intervene, taking care to leave open certain contact areas for the attachment of connecting leads. A holder structure holds the strips at each end and provides clear space for attaching connecting leads as well. The holder structure is designed to allow the flow of medium to pass in good thermo contact with the portion of the device enclosing the resistance elements.
