Abstract
<jats:p>Carotenogenesis, composition and ratio of individual carotenoid components synthesized by Rhodotorula glutinis BIM Y-159 was investigated. It was found that peak level of carotenoid production (5.7 mg/g biomass) was reached during submerged fermentation of yeast in media with high concentration of carbohydrates (glucose 11 %) and deficiency of nitrogen nutrition. Cu2+ ions in concentration 0.5 mM stimulated production of carotenoids in R. glutinis BIM Y-159 by 17.5–17.8 %. Under optimal conditions the produced carotenoid complex is represented by torulene, torulorhodin, ζand β-carotenes plus an unidentified component. β-Carotene, torulene, and torulorhodin amount for 16 %, 40 % and 32 % of carotenoids synthesized by R. glutinis BIM Y-159.</jats:p>
