Oleogenic yeasts under appropriate conditions produce and accumulate lipids and lipid-soluble metabolites in high amounts. This attribute is characteristic also for red yeasts that except lipids accumulate also carotenoids – natural pigments used in food industry and dietary supplements. The aim of this diploma thesis was designed as a comparative screening study of production properties of strains Cystofilobasidium capitatum, Rhodotorula glutinis, Sporobolomyces roseus and Sporobolomyces shibatanus. Choosen carbon sources were glucose and glycerol as waste by-product in biofuel industry. The best production properties were found in Cystofilobasidium capitatum and Rhodotorula glutinis. These two strains produced increased amounts of lipids as well as higher amounts of carotenoids. Strains were tested by FTIR spectroscopy that enables high-throughput, uncomplicated and accurate analysis.
