EFFECT OF LIGHT ON CAROTENOID YIELD IN FED CULTURES OF  PHAFFIA RHODOZYMA  CBS 5626

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.
