Photosynthetic and physiological properties, and photosynthetic pigment content of Pseudo-nitzschia multistriata.

The measurement of photosynthetic and physiological properties was performed on cells in the exponential growth phase, during preacclimation, the day before the experiments started. The growth rate did not change during experiments. relETRmax, maximal relative electron transport rate (in mol e− g Chl a−1 h−1); Ek, saturation light for photosynthesis (in µmol photons m−2 s−1); µ, growth rate (in d−1); Fv/Fm, photosystem II maximal photochemical efficiency. Values are means ± SD (n = 9). Chlorophyll a cellular content (Chl a, in 10−16 mol Chl a cell−1) and photosynthetic accessory pigments Chl a−1 content (in mol pigment/100 mol Chl a) measurements were performed during experiments. Fuco, fucoxanthin: Chl c, chlorophyll c1, 2, 3. Pigment data are means ± SD of the all data set (n = 135).
