CAROTENOID INTERCONVERSION IN LIGHT-DARK CULTURES OF THE DINOFLAGELLATE AMPHIDINIUM KLEBSII(1).
The carotenoid pigments of Amphidinium klebsii cultures grown in LD 12:12 light regimes were determined in cells harvested during the log phase growth in the dark and light photoperiods. The analysis of the individual pigments revealed the presence of an endogenous redox carotenoid system involving the epoxide carotenoid diadinoxanthin and an unidentified carotenoid with the properties of a dihydroxy xanthophyll.
