Air Pollution and Climate Change
Global climate change is one of the most acute environmental problems of our time. Among the methods of capturing CO2 in industrial emissions are chemical, physical and biological. The latter are based on the use of living organisms that absorb carbon dioxide in metabolic processes, and the subsequent use or burial of their biomass or their metabolic products. One variant of organisms used to capture carbon dioxide biotechnologically are microalgae. In the present study, the efficiency to capture carbon from the exhaust gas was compared for three microalgae species - Chlorella vulgaris, Scenedesmus obliquus and Spirullina platensis. A photobioreactor was assembled, consisting of transparent sealed flasks, a CO2 supply system, an oxygen removal system, and an illumination system. It was found that C. vulgaris was characterized by the largest increase in biomass (2.68 g l-1), and Sc. obliquus – by the lowest one (2.21 g l-1). The biofixation rate, the content of proteins and lipids were estimated to be 0.31, 0.26 and 0.29 g CO2 l ?1 d ?1, 64.0, 15.0 and 22.0 %, 15.0, 17.0 and 23.0 % for C. vulgaris, Sc. obliquus, and Sp. platensis, respectively.
