An analytical study of the effect of hydrodynamic mixing on the photosynthetic microorganism growth

The photosynthetic microorganism growth description is usually based on the so-called microbial kinetics, i.e. on the lumped parameter models (LPM) describing the photosynthetic response in small cultivation systems with a homogeneous light distribution [3, 6]. However, there is an important phenomenon, the so-called flashing light enhancement, which demands some other model than it residing in the artificial connection between the steady state kinetic model and the empiric one describing the photosynthetic productivity under fluctuating light condition. Nevertheless, even having an adequate dynamical LPM of microorganism growth, see e.g. phenomenological model of so-called photosynthetic factory [4, 5], another serious difficulty resides in the description of the microalgal growth in a photobioreactor (PBR), i.e. in a distributed parameter system.
