  • PROCESS FOR THE IMPROVED SEPARATION OF A HYDROPHOBIC ORGANIC SOLUTION FROM AN AQUEOUS CULTURE MEDIUM
    Publication number: 20130164797
    Abstract: A process for the improved separation of a hydrophobic organic solution from an aqueous culture medium is provided. The process includes preparing an aqueous culture medium of a metabolically active cell having a decreased activity; contacting of the aqueous culture medium with a hydrophobic organic solution comprising a substrate for biotransformation; conducting a biotransformation of the substrate; and separating the hydrophobic organic solution comprising a biotransformed substrate from the aqueous culture medium. The decreased activity of the metabolically active cell is in comparison to a wild-type of the active cell and the decreased activity is of at least of one enzyme that catalyses one reaction of ?-oxidation of fatty acids.

  • Alcohol dehydrogenase for the stereoselective production of hydroxy compounds
    Patent number: 7943356
    Abstract: The invention relates to a DNA sequence encoding an NADP-dependent alcohol dehydrogenase, to a vector containing at least one copy of the DNA sequence and to prokaryotic or eukaryotic host cells that are transformed or transfected with the DNA sequence. The invention also relates to the NADP-dependent alcohol dehydrogenase, to a method for the production and the use of the alcohol dehydrogenase and to a method for the stereoselective production of secondary alcohols.
    Type: Grant
    Filed: June 4, 2005
    Date of Patent: May 17, 2011
    Assignee: Codexis, Inc.
    Inventors: Thomas Daussmann, Hans-Georg Hennemann
  • Alcohol dehydrogenase for the stereoselective production of hydroxy compounds
    Publication number: 20090162893
    Abstract: The invention relates to a DNA molecule encoding an NADP-dependent alcohol dehydrogenase, to a vector containing at least one copy of the DNA sequence, and to prokaryotic or eukaryotic host cells that are transformed or transfected with said DNA sequence. The invention also relates to the NADP-dependent alcohol dehydrogenase as such, to a method for the production and the use of the alcohol dehydrogenase and to a method for the stereoselective production of secondary alcohols.
    Type: Application
