Zusammenfassung:The invention concerns a method of biological treatment of exhaust air in an environment whose temperature exceeds 35 °C to remove volatile organic acids and/or their derivatives, a biofilm, packing material of the biofilter and biofilter medium to implement this method. The packing material of the biofilter of the biofilter is enriched with volatile organic acid forming a secondary source of energy for immobilised organisms. The biofilm is formed by a mixture of the thermophylic strain Geobacillus caldoxylosilyticus BGSC W98A1 and the thermotolerant strain Aeribacillus pallidus in the ratio ranging from 1:5 to 5:1 and the exhaust air is supplied to the biofilter within the temperature range from 35 to 75 °C.
