Original Abstract

Biotechnology is a science-driven industry sector that use biology knowledge to make variable products. Our team is focused on understanding of role of polyhydroxyalkanoates (PHAs) in (cyano)bacterial cells and on PHAs production. PHAs are microbial polyesters accumulated by numerous prokaryotes in the form of intracellular granules. Main role of these compounds is to serve as a storage molecule. It has been discovered that the presence of PHA granules in prokaryotic cells enhances stress resistance against various environmental stress factors such as high or low temperature, freezing etc. Plastic and carbon dioxide pollution are serious problems. Carbon dioxide pollution is a topic that resonates strongly with society. More than 35 billion tons of CO2 were emitted to the atmosphere in 2021. Capture and usage of carbon dioxide together with reducing the CO2 emission per year could slow down warming of Earth surface. PHAs offer the solution to plastic pollution as they can replace cover materials of food products, single used plastics, they are biocompatible and biodegradable. The biggest problem remains their price. Bacterial strains producing PHA can grow on waste materials such as frying oil, hydrolysed grape pomace or waste glycerol. Cyanobacteria are another possible PHA producer producing PHA without any input materials because they can grow autotrophically utilizing CO2 and could help the environment at the same time. Cyanobacteria are phototrophic gram-negative bacteria belonging to the prokaryotes. They are ecologically extremely important as they are capable of oxygenic plant-like photosynthesis. Nowadays, electron microscopy (EM) is commonly the number one method used for observing both the shape and intracellular space of cells. In our research can EM provide important information on cell morphology, composition, inner structures and in some cases also of cell metabolites as PHA could be observed by EM.
