Original Abstract
Carotenogenic yeasts are non-conventional oleaginous microorganisms capable to utilize various waste substrates. In this work 4 red yeast strains (Rhodotorula, Cystofilobasidium and Sporobolomyces sp.) were cultivated in media containing crude, emulsified and enzymatically hydrolysed animal waste fat, compared with glucose and glycerol as single C-sources. Cell morphology (cryo-SEM, TEM), production of biomass, lipase, biosurfactants, lipids (GC/FID) carotenoids, ubiquinone, ergosterol (HPLC/PDA) in yeast cells was studied depending on medium composition, C-source and C/N ratio. All studied strains are able to utilize solid and processed fat. Compounds accumulated in stressed red yeasts are having great application potential and can result from valorization of animal waste fat in the biorefinery concept.
