The work is dedicated to the study of the light source influence that has been modified with AgInS2 quantum dots on the Nostoc commune culture in the photobioreactor. A model of the three-section laboratory photobioreactor has been created. It was investigated that the modification of the light source doesn't lead to the changes in the physical parameters in the photobioreactor. As a result, the light source modified with QD Ag:In = 1:20 resulted in a 1.5x increase in the biomass of N. commune. The amount of pigments were also changed: the maximum content of chlorophyll a (8.1 mg/g) was established under the conditions 3 of using a light source modified with QD Ag:In = 1:7. The increase in the amount of carotenoids was noticed regardless of the amount of indium in the modifying film. We recommend to use a light source modified with AgInS2 QDs to obtain N. commune biomass enriched with carotenoids
