  • Method for producing L-cystine by fermentation under controlled oxygen saturation
    Patent number: 9074230
    Abstract: The invention relates to a method for producing L-cystine by fermenting a microorganism strain in a fermentation medium, in which method L-cystine is precipitated in an amount of at least 70% relative to the total cysteine, characterized in that the O2 saturation of the fermentation medium is kept at least at 1% and at most at 40±3% during the formation of L-cystine.
    Type: Grant
    Filed: May 4, 2012
    Date of Patent: July 7, 2015
    Assignee: Wacker Chemie AG
    Inventors: Tobias Dassler, Anneliese Reutter-Maier, Thomas Schloesser
  • MICROORGANISM AND METHOD FOR OVERPRODUCTION OF GAMMA-GLUTAMYLCYSTEINE AND DERIVATIVES OF THIS DIPEPTIDE BY FERMENTATION
    Publication number: 20140342399
    Abstract: The invention relates to a prokaryotic microorganism strain capable of overproducing ?-glutamylcysteine and its derivatives bis-?-glutamylcystine and ?-glutamylcystine, which can be prepared from a parent strain, wherein said strain has a reduced cellular glutathione synthetase activity compared to the parent strain, and has a cellular ?-glutamylcysteine synthetase activity which is more greatly increased than in a strain with similarly reduced cellular glutathione synthetase activity.

  • METHOD FOR FERMENTATIVE PRODUCTION OF MENAQUINONE-7 USING ESCHERICHIA COLI
    Publication number: 20110195467
    Abstract: The invention relates to a method of producing menaquinone-7, characterized in that cells of an E. coli strain comprising the B. subtilis DSM 1088 hepS gene, the B. subtilis DSM 1088 hepT gene and the putative B. subtilis DSM 1088 heptaprenyl transferase gene are fermented in a fermentation medium, with menaquinone-7 being accumulated in the cells of the fermented E. coli strain.

  • DNA construct and process for the fermentative production of fusion proteins
    Patent number: 7943341
    Abstract: A DNA construct that allows the inexpensive production of a target protein in E. coli, consisting of a nucleic acid sequence encoding a signal peptide which is operably linked with a gene coding for a carrier protein which is linked with a gene coding for the target protein via a gene coding for a cleavable sequence S, wherein the gene coding for a carrier protein is the spy gene from E. coli.

  • Method for manufacturing a part out of amber as well as a part made of amber
    Publication number: 20020070474
    Abstract: In vehicle manufacturing and many other technical application areas, new technical demands, on the one hand, and customer desires for change, on the other hand, require a constant search for new materials. The present invention provides for amber to be used in vehicle parts, and for a method in which a semifinished product is first manufactured out of amber and then the semifinished product is reshaped into a three-dimensional form.
