Abstract
The invention relates to a method of improving the yield of a photobioreactor of the continuously operating recirculation type as a function of the species of micro-organism being cultured, of the thickness d of the chambers (10) of the reactor, and of the final concentration desired for the culture. In the method, transparent or respecting particles (15) are introduced into the reaction medium (11), which particles are of a density that is substantially equal to that of the reaction medium, thereby adjusting absorbance of the microorganism culture to optimum levels. The invention is mainly applicable to culturing phototropic micro-organisms.
