Table 1.

Effect of different temperatures and light Intensities on pigment composition of S.platensis. Values are means ± Standard deviation (n = 3). For each individual experiment variable means with the same letter are not significantly different (p > 0.05). PC – Phycocyanin, APC – Allophycocyanin, PE – Phycoerythrin, Chl. a – Chlorophyll a, Cart – Carotenoid.
