TABLE 5.

Overview of the average dilution rate (d⁻¹), biomass productivity (g L⁻¹ d⁻¹ and g m⁻² d⁻¹), and photosynthetic efficiency PE (%) achieved during the batch dilution runs. Average biomass productivities are given per reactor panel (g L⁻¹ d⁻¹) and for the entire prototype (g m⁻² d⁻¹). The average photosynthetic efficiency was calculated from the steady-state days on which irradiance data was available.
