Study on the Impact of Activators in the Presence of an Inhibitor on the Dynamics of Carbon Dioxide Absorption by Chlorophyll-Synthesizing Microalgae

The work demonstrates the suppression of the inhibiting effect of the carbon dioxide absorption process by chlorophyll-synthesizing Chlorella microalgae due to sulfur oxide SO₂, activators of phosphorus oxide P₂O₅ and nitrogen oxides N_xO_y The research presents the experimental dependences of the dynamics of СО₂ absorption by microalgae under the critical concentration of inhibitor SO₂ in the presence of the P₂O₅ and N_xO_y activators. The authors devised the mathematic models of growth of the Chlorella microalgae population depending on the concentration of the phosphorus oxide and nitrogen oxides activators under a permanent concentration of the sulfur oxide inhibitor. The research determined an optimal total concentration of P₂O₅ activator in the presence of the SO₂ inhibitor, as well as an optimal total concentration of the NO₂ activator in the presence of the SO₂ inhibitor.
