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.
