Starch Accumulation during Photoautotrophic Diurnal Growth.

Cells were cultivated in a diurnal cycle of 12 h light/12 h dark in a controlled incubation chamber supplied with 2% CO₂ in air. Light was supplied via fluorescent tubes at an intensity of 100 µmol m⁻²s⁻¹. Values are the mean of biological replicates (i.e., independent shaking flask cultures; n = 4, sd). Shaded area refers to the night period.
