AB Maximal productivity of a 14 mm light-path panel photobioreactor under high irradiance wasdetermined. Under continuous illumination of 2100 μmol photons m-2 s-1 with red LEDs (lightemitting diodes) the effect of dilution rate on photobioreactor productivity was studied. Thelight intensity used in this work is similar to the maximal irradiance on a horizontal surface atlatitudes lower than 37º.Chlorella sorokiniana, a fast-growing green microalga, was used as a reference strain in thisstudy. The dilution rate was varied from 0.06 h-1 to 0.26 h-1. The maximal productivity wasreached at a dilution rate of 0.24 h-1, with a value of 7.7 g of dry weight m-2 h-1 (m2 ofilluminated photobioreactor surface) and a volumetric productivity of 0.5 g of dry weight L-1 h-1. At this dilution rate the biomass concentration inside the reactor was 2.1 g L-1 and thephotosynthetic efficiency was 1.0 g dry weight per mol photons. This biomass yield on lightenergy is high but still lower than the theoretical maximal yield of 1.8 g mol photons-1 whichmust be related to photosaturation and thermal dissipation of absorbed light energy.
