Originální abstrakt

Haloferax mediterranei is extremely halophilic archeon capable of production of two very interesting biopolymers. This microorganism intracellularly accumulates polyhydroxyalkanoates (PHA) while simultaneously excreting polysaccharide. In this work we focused on production and characterization of its extracellular polysaccharide. To decrease cost of the cultivation media we substituted expensive yeast extract by alkaline hydrolyzed waste chicken feather which positively influenced polysaccharide yields.Moreover, isolated polysaccharide was capable to provide very high protective activity for model prokaryotic (Cupriavidus necator) and eukaryotic (Saccharomyces cerevisiae) microorganisms against various stress factors such as freezing, ethanol, high temperature, osmotic pressure, oxidative pressure induced by H2O2 or SDS which imply its interesting biological properties and potential applications in biotechnology or health care.
