The efficiency of photobiosynthesis at various densities of Spirulina platensis culture was obtained. The energy absorption coefficients were calculated from the absorption spectrum of the culture and the emission spectrum of the light grid. It was shown that the photobiosynthesis efficiency increases with the growth of the culture density, reaching a maximum value of 5.09% in the linear section. The drawback of the calculations is a priori constant value of caloric value of the biomass.
