A mathematical formulation of a model of an airlift photobioreactor in the cases of interphase mass transfer between gas and liquid in the riser and photobioreaction in the downcomer is presented. The equations allow the calculation of the vertical distribution of the average concentrations of an active gas component (CO 2, O 2) and a photoactive material (cells), using average velocities and effective diffusivities in the riser and the downcomer. A hierarchical approach for the model parameter identification on the basis of experimental data is proposed.
