  • Metabolically enhanced cyanobacterial cell for the production of ethanol
    Patent number: 9493794
    Abstract: A metabolically enhanced cyanobacterial cell for the production of ethanol is provided. The metabolically enhanced cyanobacterial cell for the production of ethanol comprises at least one recombinant gene encoding a pyruvate decarboxylase enzyme (Pdc) converting pyruvate to acetaldehyde, and at least one recombinant gene encoding a first Zn2+ dependent alcohol dehydrogenase enzyme (Adh) converting acetaldehyde to ethanol. The invention also provides a method for producing the metabolically enhanced cyanobacterium, a method for producing ethanol with the metabolically enhanced cyanobacterium, and a method for screening of alcohol dehydrogenase enzyme expressing cyanobacterial strains for the presence of NADPH-dependent native alcohol dehydrogenase enzymes.
    Type: Grant
    Filed: May 21, 2015
    Date of Patent: November 15, 2016
    Assignee: Algenol Biotech LLC
    Inventors: Ulf Dühring, Heike Enke, Karl Ziegler, Torsten Schwecke
