THE DEFINITION OF EFFICIENCY PHOTOBIOSYNTHESIS AT DIFFERENT DENSITIES OF THE SPIRULINA PLATENSIS CULTURE’’

The study investigates the efficiency of photobiosynthesis in Spirulina platensis at varying culture densities. Utilizing tools like the KFK-2 colorimeter and Uniko 4802 spectrophotometer, researchers measured key parameters such as the energy absorption coefficient and caloric value of the biomass.
