- Abstract
An axenic clonal culture of Chattonella antiqua (Hada) One was grown on a 12:12 h LD cycle in a laboratory culture tank containing 1 m[SUP5] of &fracf2; medium. Diet changes in mean cell volume, cellular carbon (carbon content per cell). C/N ratio, cellular Chl a, Chl a/c ratio and carotenoid composition were observed. Mean cell volume and cellular C. N and pigments increased during the light period as a result of photosynthesis and decreased with increase of cell concentration by phased cell division during the dark period. These changes indicated that carban assimilation and pigment synthesis occurred together during the light period. However, the patterns of increase were not the same since different diet patterns were also found in the ratios of C / N and chi a/c. Photosynthetic pigments were analyed by reversed-phase high-performance liquid chromatography with ion-pairing solution. This analysis showed that the dominant carotenoids in C. antiqua were fucoxanthin, violaxanthin and β-carotene. Diel patterns of Chis a and c were similar to that of fucoxanthin but different from those of violnxanthin and β-carotene. The cellular contents of Chl a, fucoxanthin and carbon increased in a parallel manner during the light period, On the other hand, the increase of violaxanthin was restricted to only a few hours at the beginning of the light period during cell division cycles.
