The oxygen evolution characters of Scenedesmus dimorphus under attached cultivation for different days of cultivation. (A) The oxygen evolution rate versus light intensity (light curve) of S. dimorphus under attached cultivation for 0 (black circle), 2 (white circle), 4 (black down-pointing triangle), 6 (white down-pointing triangle), 8 (black square), and 10 (white square) days of cultivation. Data were mean ± standard deviation of six measurements for three independent experiments (two measurements for each). (B) The light compensation point of S. dimorphus under attached cultivation for different days of cultivation. The ANOVA (SPSS, Chicago, IL, USA) result indicated that there were no differences for different days.
