Abstract

The invention provides a genetically modified Cyanobacteria having a construct comprising DNA fragments encoding pyruvate decarboxylase (pdc) and alcohol dehydrogenase (adh) enzymes obtained from the Zymomonas mobilis plasmid pLOI295. The Cyanobacteria are capable of producing ethanol in recoverable quantities of at least 1.7 &mgr;mol ethanol per mg of chlorophyll per hour.
