Samples were taken from different nitrogen sources and of different concentrations, with addition of various concentrations of CO2 and in the presence of salt. The best biomass productivity was achieved using urea as a nitrogen source or modified growing medium BG11 with decreased concentration of NaNO3. The positive impact on the growth of biomass was achieved by aeration with CO2 (especially with concentration of 24%). Additional research into the removal of pollutants, such inorganic salts of nitrogen and phosphorus and organic materials from wastewater using microalgae has revealed good possibilities of using both algae strains in wastewater treatment plants. A content of oil in Chlorella sp. and Scenedesmus sp. has suggested their potential use as biodiesel feedstock. Key words: microalgae, biomass, growing conditions, CO2 fixation. 1. Introduction The study of different aspects related to the behavior of microalgae has received renewed interest due to the wide field of application of these microorganisms. Algae cultures have been principally developed as an
