(A) Changes in the optical density of CCAP 19/30 cultures within 48 h period when growing under 12/12 LD conditions. (B) Changes in the cell density of CCAP 19/30 cultures within 48 h period when growing under 12/12 LD conditions. (C) Changes in the mean forward-angle light scatter (FSC-A) signals of CCAP 19/30 cells within 48 h period when growing under 12/12 LD conditions monitored by flow cytometer. (D) Standard curve of mean FSC-A signal to particle size showing that mean FSC-A signal is highly correlated with particle size. All cultures were grown at 25 °C with continuous shaking (100 rpm). The light intensity during the light periods of all conditions was 200 μmol photons m⁻² s⁻¹. Cultures in each condition were set up at least in triplicate.
