Figure 3. Growth curves monitored in 96 well plates, measuring cell concentration with flow cytometry.

Cell concentration (cells/µL) was estimated from flow cytometry events, calibrated using CountBright Absolute Counting Beads (Invitrogen). Error bars are SEM (n = 3). (a) Chlamydomonas reinhardtii strain 137c at initial cell concentration of 10⁶ cells/mL (○). (b) C. reinhardtii strain 137c at initial cell concentration of 2.5×10⁵ cells/mL (•). (c) Chlorella vulgaris at initial cell concentration of 10⁶ cells/mL (□). (d) C. vulgaris at initial cell concentration of 2.5×10⁵ cells/mL (▪).
