Original Abstract

Carotenogenic yeasts are group of oleaginous microorganisms capable of utilizing various waste substrates from food and agricultural industry. They are well known for the production of carotenoids, lipids and other valuable metabolites, which can be further used in pharmaceutical, food and feed industry. Thus, enriched biomass produced on the waste substrates can be used as a part of circular economy model. In this work, four red yeast strains (Rhodotorula, Cystofilobasidium, and Sporobolomyces sp.) were tested on media containing whey and waste animal fat with different C/N ratios. Results show that all tested strains were able to utilize used waste substrates and produce high amounts of studied metabolites due to stress induction by waste substrates. Result show, that yeasts prefer lower C/N ratio for biomass and carotenoid production. On the other hand, higher lipid content was observed in C/N ratios above 50. In overall the best yeast genera was Rhodotorula, which were able to grow steadily on all media types and all C/N ratios.
