Experimental Substantiation of the Use of a Biological Agents Tolerant to Elevated Carbon Dioxide Concentration

Six biopreparations containing microalgae of the genus Chlorella and Spirulina were investigated for their possible use in utilization of carbon dioxide from industrial emissions. The adaptive abilities of microalgae to nutrient media, intensification of growth and development of the most viable culture of microalgae at increasing concentration of carbon dioxide, its resistance to the gas formed as a result of tests of power plant containing methane and the potential of this culture of microalgae in reducing the level of CO 2 in model flue gases were evaluated. It was confirmed that the biopreparation “SPIRULINAFOOD” (Chlorella sp.) has high viability and provides growth of microalgae cultures in conditions of increased content of CO 2 and methane, showing the efficiency of CO 2 removal from model flue gases comparable with the efficiency of natural consortium of microalgae – up to 15 %.
