Original Abstract

Carbon dioxide pollution is a topic that resonates strongly with society. More than 35 billion tons of CO2 were emitted to the atmosphere in 20211. Capture and usage of carbon dioxide together with reducing the CO2 emission per year could slow down warming of Earth surface. Polyhydroxyalkanoates (PHAs) are microbial biopolymers, occur as an intracellular granules and serve as an energy storage compound. They are biodegradable, UV resistant and biocompatibile2. PHA itself are fragile, the properties can be improved by incorporating other monomers into the structure resulting in in-vivo copolymer synthesis. PHA production is financially demanding. For heterotrophic bacteria waste materials serve as a carbon source. As the cyanobacteria are capable of oxygenic photosynthesis, they do not demand carbon source and for PHA synthesis they need only CO2 and light source. Cyanobacteria are phototrophic gram-negative bacteria belonging to the prokaryotes. They are ecologically extremely important as they are capable of oxygenic plant-like photosynthesis. Thanks to this ability cyanobacteria played a key role in biological and in geological history of our planet. Cyanobacteria synthesize many biologically active secondary metabolites such as glycogen, pigments, lipids or PHAs3.
