Bioprocesses with four different light regimes were characterized in triplicates by the cultivation of strain S07004. Light intensity (height) and exposure time (width) are indicated as blue shaded areas. For full intensity, the light intensity was set to 545 µm quanta m⁻² s⁻¹, while half intensity reached 250 µm quanta m⁻² s⁻¹. For the no blue light control, fermenter vessels were shielded from neighboring blue light but were still affected by ambient light. For the late induction experiment, full light intensity was switched on 16 h after inoculation. a DO concentration in the percentage of representative cultivations. b Cell dry weight measurements in mg/L of the bioreactor cultivations in triplicate were joined and the deviation of the mean is indicated by ribbons. c Total intracellular hydrocarbon titer determined in triplicate
