Relationship of light intensity (PPFD at BS) and cell density (cell growth condition) for each experiment: a Experiment 1 at initial 200–220 μmol m−2s−1 and photoperiod 12:12 h, b Experiment 2 at initial 350–370 μmol m−2s−1 and photoperiod 12:12 h, and c Experiment 3 at initial 350–370 μmol m−2s−1 and photoperiod 18:6 h
