“…In the shade adapted cells, diatoxanthin was present in trace amounts; in accordance with the findings of Demers et al (1991). This pigment composition supports other analyses of peridinin-containing dinoflagellates (Johansen et al 1974, Jeffrey et al 1975, although the peridinin related xanthophylls, pyrroxanthin and pyrroxanthinol (Johansen et al 1974) were not detected in our Alexandrium isolates. In addition, the method here employed showed minor amounts of divinyl protochlorophyllide a (MgDVP) and trace amounts of chlorophyll c 1 , which is in agreement with the results obtained by Zapata et al (1998) for another strain (ALV1) of Alexandrium minutum.…”

“…Our study indicates that diadinoxanthln is the second most abundant carotenoid in dinoflagellates (Johansen et al 1974, Johnsen & Sakshaug 1993 as it is in most chromophytes (Rowan 1989). In low light, both species increased the cellular content of light-harvesting pigments relative to high-light adapted cells (Prezelin 1976, 1981, Demers et al 1991, Sakshaug et al 1991, Johnsen & Sakshaug 1993).…”

Pigment-and chromoprotein-dependent spectral models, designed to accurately reconstruct whole cell absorption spectra for photosynthetic dinofldgellates, were assessed. Measured spectral absorption properties (400 to 700 nm) included signatures from whole cells, dispersed thylakoid fragments (unpacked absorption), isolated chromoproteins and individual pigments from high (500 pm01 m-2 S-') and low (35 pm01 m-2 S") light-adapted cells of the dinoflagellates Prorocentrum minimum and Heterocapsa pygmaea grown in continuous light at 15 OC. For model verification, we also developed a procedure to measure unpackaged cell absorption, free of solvent and light-scattering effects. Maximum measured chl a-spec~f~c absorption at 675 nm appears to be closer to 0.027 than a predicted value of 0.0203 m2 mg-l chl a based on absorption from chl a in 90% acetone. The percent fractional absorption of 'in vivo' welght-specific absorption coefficients of individual pigments relative to total weighted absorption (all pigments) was estimated to indicate the light-harvesting capabilities of the different pigments as a function of photoadaptive status and water color. Correspondingly, the weighted absorption of each pigment fraction has been estimated in theoretical white light and in 'clearest' green coastal and blue oceanic waters. Independent of water color, peridinin was by far the most important light-harvesting pigment, followed by chl c2 and chl a. The photoprotective diadinoxanthin absorbed most efficiently in the blue part of the visible spectrum. Results indicate that the chromoprotein model (1) overcame spectral distortions inherent in more general pigment-dependent models and, when combined with corrections for pigment packaging effects. (2) provided accurate spectral estimates of in vivo absorption coefficents and (3) worked equally well for dinoflagellate species with or without the major light-harvesting peridinin-chlorophyll-protein complex, PCP. Findings are discussed in the context of modeling of blo-optical characteristics in dinoflagellates, their photoecology and implications for the in situ optical monitoring of red tides.

“…Diatoxanthin, the non-epoxidic derivative of the xanthophyll-cycle (Johansen et al 1974, Hager 1980, Hallegraeff et al 1991, was not encountered in this study ; the presence of this carotenoid is largely depending on environmental conditions. The hydrophile carotenoids P 457 und P 468 (Johansen et al 1974, Goodwin & Britton 1988 were detected in all studied strains. P 457 has been shown to be a derivative of neoxanthin containing lactoside in the molecule.…”

“…Found in minor quantities was ß-carotene ; diatoxanthin was not encountered. The hydrophile carotenoids P 457 and P 468 (nomenclature after Johansen et al 1974) were also detected (Goodwin andBritton 1988, Jeffrey et al 1997). Pyrrhoxanthin and pyrrhoxanthinol were identified with reservation.…”
