Fig. 3: Distribution of chlorophyll-containing cells and dead cells in Experiment 7.

Dead cells stained by propidium iodide (PI+; cluster on the right) with an indication of the percentage of dead cells among chlorophyll-containing cells (ntotal). Treatments include the initial culture (a, ntotal = 0.9 × 109 cells), after water homogenization (b, ntotal = 1.6 × 109 cells), after SJ9 treatment (c, ntotal = 2.4 × 109 cells), and after MJ3 treatment (d, ntotal = 2.4 × 109 cells).
