Original Abstract

Carotenogenic yeast are group of yeast known for production of yellow-red pigments called carotenoids. Red- pigmented yeast are also known for production of immuno-active beta-glucans within their cell walls. Industrially interesting is also their ability of accumulation of high amount of lipids as well as of production of many lipid- soluble compounds such as provitamin D (ergosterol) and coenzyme Q (ubiquinone). Thus, carotenogenic yeast strains are very promising for pharmaceutical or food industry. Due to their high adaptability they can grow within harsher conditions of artificial media with waste substrates. This research is aiming for usage of combination of waste poultry fat and purified glycerol as carbon sources in media and cobalt in the form of Co2+ as terminal stressor added in exponential phase of growth to achieve substantial biomass growth and metabolite production. This method of cultivation was tested on genus Sporidiobolus pararoseus which achieved higher biomass growth on media with waste poultry fat (22,4 g/l) than on control with glycerol as carbon source. The best growth of biomass was recorded in media with poultry waste fat with addition of cobalt in exponential phase (25,4 g/l). The main goal is the completion of screening phase of experiments where more of genera, such as Rhodosporidium, Rhodotorula or Cystofilobasidium, will be tested and the best cultivation conditions will be subjected to scale-up process into laboratory bioreactor.
