FIG. 10.

Near the growth light intensity, q_N reaches a minimum for a wide range of cyanobacterial strains and culture conditions. Mean values are plotted for strains grown at 5 (n = 3), 10 (n = 5), 15 (n = 6), 35 (n = 1), 50 (n = 20) and 150 (n = 3) μmol of photons m⁻² s⁻¹. The strains were Anabaena/Nostoc sp. strain 7120, Calothrix sp. strain PCC 7601, Nostoc sp., Pseudanabaena sp. strain PCC 6901, Synechococcus sp. strain PCC 7942, Synechococcus sp. strain PCC 6301, and Synechocystis sp. strain PCC 6701.
