- Аннотация: Decarbonization of the power industry requires the search of methods for cutting down the greenhouse gas emissions into the environment, including utilization of carbon dioxide generated during combustion of hydrocarbon fuels at power facilities. One of the promising methods is the capture of carbon dioxideby biota, not only by terrestrial plants but also by aquatic organisms, including specially cultivated microalgae.In this work, the efficiency of the capture of carbon dioxide with a concentration of approximately 6% froma gas–air mixture by Arthrospira platensis (Nordst.) Geitl microalgae was studied. This concentration has beenselected on the basis of experimentally determining the CO2 content in flue gases formed at industrial gaspiston power plants. The experiments were performed using a closed photobioreactor with a capacity of100 dm3 installed in a gas chamber enabling elevated СО2 concentrations in an air–gas environment to be created. The maximum growth rate of the microalgae biomass is 0.140 g/(dm3 day). The effectiveness of CO2capture by microalgae was 0.220 g/(dm3 day) based on the results of determination of the microalgae productivity by biomass and 0.235 g/(dm3 day) based on the results of direct measurement of СО2 concentration inthe chamber. The concentration of the main nutrients (such as bicarbonates, phosphates, and nitrates) in themedium decreased by 25–50% during the experiment period. A comparative analysis of the consumption ofcarbon-containing components of the medium ( ) by microalgae during the bubbling of culturalliquids with a gas–air mixture with different carbon dioxide content was performed. In general, good viabilityof A. platensis microalgae (high quality of biomass and high rate of its growth) was demonstrated when it wascultivated in an atmosphere with a high concentration (6%) of CO2
