The Influence of Operating Conditions on the Growth of the Yeast Rhodotorula Rubra ICCF 209 and on Torularhodin Formation

The aim of the present work is to study the formation of the intracellular carotenoid pigment torularhodin depending on culture medium composition and other cultivation factors. The paper presents the influence of shaker cultivation conditions on the growth and torularhodin formation of the yeast Rhodotorula rubra ICCF 209 and the procedure for the extraction, separation, and quantitative determination of the carotenoids, mainly beta-carotene and torularhodin, with antioxidant potential characteristics.
