This diploma thesis follows to the bachelor thesis Utilization of Algae in Biogas Trans-formations, which was rather a research type and dealt with the removal of carbon diox-ide by photosynthesis of algae from biogas. The aim of this thesis is to examine the issue of undesirable substances in biogas, mainly hydrogen sulfide, and to verify the possibil-ity of using Chlorella pyrenoidosa Chick (IPPAS C2) for the biogas treatment. This ver-ification is based on scientific studies and hypotheses. This culture was grown in the proposed laboratory system in BG11 medium and in BG11 medium with reduced SO4-2 sulfate salts for eight days and nine days. Based on the results of the culture parameters, sulphate formation in the nutrient medium has been proven to be dependent on pH and oxygen. During the measurement, the decrease of hydrogen sulfide concentration was recorded after application of the given culture apparatus. The loss of hydrogen sulfide occurred due to absorption into the nutrient medium. The hypothesis of the ability of algae to consume the resulting sulfate from the medium for their own use has not been confirmed.
