Characterisation of model cultures grown under three different light intensities. (A) Cell number based on suspension volume plotted against time. Means ± SD are given (n = 4). (B) Starch content per 1 million cells obtained by extraction. Developmental cycle of the synchronized algal cells and the duration of the light and dark phase is schematically visualized on top of A and B. (C) Correlation of starch content obtained by extraction and mean of SSC signals derived from flow cytometry. Correlation analysis was based on the time points: 0, 3, 6, 9, 12, 15, and 24 h. Development of SSC and starch content was plotted after normalisation. Means ± SD are shown (FC: n = 2; extraction: n = 4)
