Abstract
The present invention discloses genetically-modified cyanobacteria with ethanol-production capabilities enhanced over the currently-reported art, and methods of making such cyanobacteria. The invention provides a genetically modified photoautotrophic, ethanol producing host cell comprising an overexpressed pyruvate decarboxylase enzyme converting pyruvate to acetaldehyde and an overexpressed Zn2+ dependent alcohol dehydrogenase enzyme converting acetaldehyde to ethanol.
