INFLUENCE OF NUTRIENT MEDIUM COMPOSITION ON THE SPECTRAL PROFILE OF CAROTENOIDS IN YEASTS OF THE GENERA RHODOTORULA, SPOROBOLOMYCES, CYSTOBASIDIUM

Gribanova Ekaterina Aleksandrovna  (PhD student, Senior Lecturer BSU, Minsk, Belarus )

In the presented study, the spectral profile of carotenoid pigments produced by psychrotolerant yeasts of the genera Rhodotorula (3 strains), Sporobolomyces (6 strains), and Cystobasidium (2 strains) was studied. The analysis showed that the composition of the nutrient medium affects not only the amount of synthesized pigments, but also their profile. It was noted that the total yield of carotenoids during growth in a medium with the addition of corn flour was 1,6–2,2 times more than in Sabouraud's medium and 2,0–6,1 times more than during growth in TSB broth.
