ABSTRACT
The aim of this study was to evaluate the influence of light on the production of carotenoids by Phaffia rhodozyma CBS 5626 yeast. The fed-cultures at different illuminance were conducted: in the dark, at constant illuminance of 400 lux and 600 lux, at variable illuminance. It was found that illuminance and time had a significant effect on the level of carotenoids synthesized by Phaffia rhodozyma CBS 5626. But these agents had no a significant effect on yeast dry matter yield. Light stimulated carotenogenesis in cells of the tested yeast; the highest yields of carotenoids were obtained in cultures run at illuminance of 400 lux, while the lowest in cultures run in the dark.
