  • METABOLIC ENGINEERING OF ARABINOSE-FERMENTING YEAST CELLS
    Publication number: 20120208231
    Abstract: The invention relates to an eukaryotic cell expressing nucleotide sequences encoding the ara A, ara B and ara D enzymes whereby the expression of these nucleotide sequences confers on the cell the ability to use L-arabinose and/or convert L-arabinose into L-ribulose, and/or xylulose 5-phosphate and/or into a desired fermentation product such as ethanol. Optionally, the eukaryotic cell is also able to convert xylose into ethanol.

  • FERMENTATIVE GLYCEROL-FREE ETHANOL PRODUCTION
    Publication number: 20110275130
    Abstract: The present invention relates to a yeast cell, in particular a recombinant yeast cell, the cell lacking enzymatic activity needed for the NADH-dependent glycerol synthesis or the cell having a reduced enzymatic activity with respect to the NADH-dependent glycerol synthesis compared to its corresponding wild-type yeast cell, the cell comprising one or more heterologous nucleic acid sequences encoding an NAD+-dependent acetylating acetaldehyde dehydrogenase (EC 1.2.1.10) activity. The invention further relates to the use of a cell according to the invention in the preparation of ethanol.

  • Pyruvate producing yeast strain
    Patent number: 7405068
    Abstract: Disclosed herein are glucose tolerant C2 carbon source-independent (GCSI) yeast strains having no detectable amount of pyruvate decarboxylase activity, wherein wild type yeast strains for the glucose tolerant C2 carbon source-independent yeast strains are Crabtree positive. Also disclosed are methods of selecting glucose tolerant C2 carbon source-dependent yeast strains, and methods of producing pyruvic acid or salts thereof using glucose tolerant C2 carbon source-independent yeast strain. Further disclosed herein are GCSI yeast strains having a genome that comprises an exogenous lactate dehydrogenase gene.
