Original Abstract

Cyanobacteria are ecologically important phototrophic gram-negative which belong to prokaryotes. Cyanobacteria synthetize many interesting metabolites such as glycogen, lipids, carotenoids or polyhydroxyalkanoates (PHA). PHA are biodegradable biopolymers with similar properties as petrochemical plastics and they occure in bacteria in granules. Numerous prokaryotes including cyanobacteria use PHA as a storage of carbon and energy in form of intracellular granules. The most common type of PHA is poly-3-hydroxybutyrate (PHB). PHA can be produced by heterotrophic bacteria as well, such as Cupriavidus necator H16 or Methylobacterium rhodesianum. PHB raises fitness of bacteria because it helps the bacteria to survive the stress conditions – osmotic stress, UV radiation or freezing. Both strains are capable of co-polymer synthesis in presence of its structural precursor. The composition of co-polymer differs in Synechocystis sp. PCC 6803 and Synechocystis salina CCALA 192 and the composition of co-polymers also varies depending on the precursor concentration. 4HB was for the first time in cyanobacteria reported in Synechococcus sp. PCC 7002 in 2015 an in PCC 6803 in 2020.
