Variations in pigment contents of the diatom Phaeodactylum tricornutum during growth

Changes in the amounts of chlorophyll a, chlorophyll c, fucoxanthin, diadinoxanthin and β-carotene were determined during Phaeodactylum tricornutum growth. The transition of the culture from the logarithmic to the stationary phase is accompanied by an increase in the carotenoids: chlorophyll a ratio...
