Beschreibung
Zusammenfassung:	One embodiment of the invention provides a genetically enhanced cyanobacterium producing a first chemical compound comprising: a genetically enhanced genome with a first gene inactivation in a first essential or conditionally essential gene of the cyanobacterium, and a first extrachromosomal plasmid harboring the first essential or conditionally essential gene and at least one first production gene for production of the first chemical compound, wherein the cyanobacterium lacks a functional gene conferring biocide resistance. These cyanobacteria can produce a first valuable chemical compound in long-term cultures without the need to employ genes conferring biocide resistance.
