Abstract:

Microalgae are a large group of predominantly unicellular organisms with wide adaptability to diverse environmental conditions. The adaptation is associated with the production of valuable compounds: pigments, which show a wide range of applications. One of these pigments is fucoxanthin with a positive effect on human health. Fucoxanthin is an especially strong antioxidant. Currently, fucoxanthin is obtained mainly from macroalgae, although fucoxanthin content is higher in microalgae. The obstacle for fucoxanthin production from microalgae is the high costs of production and subsequent processing. Therefore, the optimization of cultivation conditions to reduce production costs is a priority. The master thesis focuses on certain microalga which has shown to have high potential in fucoxanthin yield. The microalga produces besides fucoxanthin also eicosapentaenoic acid and docosahexaenoic acid. The master thesis is introducing the results of microalgal performance during experiments testing various cultivation conditions. All experiments were done during an internship at the Centre ALGATECH, Institute of Microbiology of the Czech Academy of Sciences.
