Using of algae in a biogas transformation is still in the beginning. However, the microalgae have large potential from the perspective of growing demands on biogas quality and trend of using,natural resources. First of all, it is their ability to fix carbon dioxide (CO2) using photosynthesis and presumed ability of some algae to metabolize hydrogen sulphide (H2S). Biogas contains not only required methane but also components causing its worse quality such as mentioned CO2 and H2S. Therefore, the algae are potential biological systems for biogas-conditioning. The microalga Chlorella pyrenoidosa Chick (IPPAS C2) was used for fixation of CO2 and H2S in our experiment. The microalgae were cultivated in a medium BG 11. The algal suspension was aerated with the biogas during two weeks. Different values of CO2 concentration measured in the input and output confirmed decrease of CO2 caused by intensive growth of algal culture. Decline of H2S was not confirmed.
