  1. Batch TAG content (f TAG, batch ), batch (P TAG, batch ) and maximum (P TAG, max) TAG productivity, and maximum TAG yield on light (Y TAG, ph, max ) obtained for the different initial biomass concentrations (C x (0)) and average light intensity (I av ). In brackets, day at which maximum TAG productivity and TAG yield on light were obtained.
