Recombinant cyanobacterium expressing a transcription factor domain protein

A recombinant cyanobacterium comprising an exogenous nucleic acid molecule encoding a transcription factor domain protein,

• wherein the transcription factor domain protein has transcription factor activity and comprises an amino acid sequence having at least 85% amino acid sequence identity to the amino acid sequence of SEQ ID NO:14 or SEQ ID NO:16, and
• wherein the recombinant cyanobacterium further comprises at least one additional exogenous nucleic acid molecule encoding an enzyme selected from the group consisting of an acetyl CoA carboxylase, a ketoacyl-CoA synthase, an acyl-CoA synthetase, a fatty acyl-CoA/aldehyde reductase, an alcohol-forming fatty acyl-CoA reductase, a fatty aldehyde-forming fatty acyl-CoA reductase, an acyl-ACP reductase, a carboxylic acid reductase, a fatty aldehyde reductase, an alcohol acetyl transferase, an acyl-CoA alcohol transacylase, an acyltransferase, a wax synthase, a fatty aldehyde decarbonylase, and a fatty acid decarboxylase, and
• further wherein the recombinant cyanobacterium produces a greater amount of at least one free fatty acid or at least one fatty acid derivative than does a control cyanobacterium that does not comprise the exogenous nucleic acid molecule encoding the transcription factor domain protein, and
• still further wherein the exogenous nucleic acid molecule is operably linked to a promoter that is heterologous relative to the cyanobacterium and/or the exogenous nucleic acid molecule.
