Original Abstract

Carotenogenic yeast, which are also called oleaginous, are microorganisms capable of accumulating significant amounts of carotenoids, lipids, and glucans into their biomass. Their ability of processing waste materials and different carbon sources from various industries, such as agricultural industry, provides the possibility to use them for waste material treatment. This waste treatment process then could be used as a part of circular economy cycle. This research is focused on optimization of cultivation process in Erlenmeyer flasks by changing cultivation conditions and media composition as well. Research is focused on carotenogenic yeasts, especially the genus Rhodotorula, Cystofilobasidium and Rhodosporidium which have achieved significant results with interesting biomass growth (above 20 g/l). The optimization process is focused predominantly on mineral media with addition of animal by-products, namely poultry waste feathers and fat. Hydrolysed feathers play a major role as nitrogen source and waste fat serves as carbon source.
