Abstract
One embodiment of the invention is directed to a genetically enhanced cyanobacterium for the production of a first chemical compound, comprising at least one first recombinant gene encoding a first biocatalyst for the production of the first chemical compound, wherein the gene is under the transcriptional control of a Co2+ or Zn2+-inducible promoter. Such a cyanobacterium can provide a tighter control of the production of the first chemical compound.

An ethanologenic recombinant cyanobacterium comprising a recombinant alcohol dehydrogenase gene and a heterologous pyruvate decarboxylase gene wherein said alcohol dehydrogenase gene is operably linked to a first promoter and wherein said pyruvate decarboxylase gene is operably linked to a second promoter and wherein said second promoter is a Co2+ inducible promoter or a Zn2+ inducible promoter.
An ethanologenic recombinant cyanobacterium comprising a recombinant alcohol dehydrogenase gene and a heterologous pyruvate decarboxylase gene wherein said alcohol dehydrogenase gene is operably linked to a first promoter and wherein said pyruvate decarboxylase gene is operably linked to a second promoter and wherein said second promoter is a Ni2+ inducible promoter.
