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 ( ) of the reactor, and of the final concentration desired for the culture. In the method, transparent or respecting particles ( ) are introduced into the reaction medium ( ), 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.
