Biomass yield on light, TAG content, TAG production rate and productivity as functions of IBS-light availability. Biomass yield on light (Y _{x, ph, batch} ; a), TAG content (f _{TAG, batch} ; b), initial-biomass-specific TAG production rate (r_{TAG, IBS, batch}; c) and TAG productivity (P _{TAG, batch} ; d) at the end of the batch at increasing initial-biomass-specific light availabilities (I _{IBS, batch} ) for the different runs in vertical (black diamonds) and horizontal (white circles) reactors.
