The carotenoid pigments of Euglena gracilis were studied following illumination of the cells under aerobic and anaerobic conditions. Cells harvested from cultures in the stationary phase displayed a photochemical conversion of epoxide carotenoids to non-epoxide pigments under anaerobic conditions. This reaction was reversed in the dark and could be inhibited by aerobiosis. Analysis of the individual pigments indicated that the following reaction was occurring: Carotenes, neoxanthin and trollein remained essentially unchanged under these conditions.
