Beschreibung
Zusammenfassung:	The basis of the present invention is a method of reducing the level of carbon dioxide during the biological purification of biogas conducted in devices for the purification of biogas, particularly a biofilter loaded with a biological filter bed sprinkled with a mineral medium, containing immobilised microorganisms capable of degrading hydrogen sulphide, based on the fact that the process is conducted under anoxic conditions using a consortium of microorganisms collected from sulphur-rich natural environments, the biological filter bed is sprinkled with a medium in the form of a solution containing nitrates of alkali metals of the I and II group, wherein the concentration of nitrate ions in the medium is in the range of 20 to 2500 mg/l, preferably in the range of 50 to 1000 mg/L.
