Original Abstract

Presented work is focused on growth, metabolic and production activity of several non-conventional red yeast strains of the genus Rhodotorula, Sporobolomyces and Cystofilobasidium cultivated on some lignocellulose wastes as pre-treated whey straw, pine hydrolyzates and rapeseed cake. The main aim of the current investigation was to assess the potentialities of red yeasts to transform these waste substrates to high-value products. Biotechnological production of targeted metabolites will be compared between individual analyzed strains. Cellular and molecular changes of red yeast cells cultivated under nutrition depletion will be discussed too. Production properties of red yeasts will be studied also during scale-up process in 5-L laboratory fermentor. The yields of about 30 g per liter of biomass enriched by 30-50 mg of total carotenoids and about 50 mg of ergosterol were obtained by the most producing strains.
