Potential use of waste lipid substrates and glycerol to production of carotenoids by yeasts
 Kostovová, Iveta ; Obruča, Stanislav (referee) ; Márová, Ivana (advisor)
The aim of this study was use of lipid waste substrates and waste glycerol as carbon sources for red yeasts. Six yeast strains, namely Rhodotorula glutinis, Rhodotorula rubra, Rhodotorula aurantiaca, Cystofilobasidium capitatum, Sporobolomyces roseus and Sporobolomyces shibatanus were used for cultivation. All studied yeast strains were able to utilize glycerol and rapeseed oil as a carbon source. Cultivation in oil medium was in most of strains accompanied by decreased production of carotenoids. Increased production of ergosterol, lycopene and biomass was observed in some strains only. Most of yeast strains cultivated in glycerol medium produced increased amount of biomass as well as carotenoids. The best producer of bi-omass and pigments was yeast strain Sporobolomyces roseus CCY 19-6-4 grown in medium containing glucose and glycerol in a 1:1 ratio.
