Abstract

This study investigated the influence of the temperature on methane (CH4) oxidation and respiration in compost sampled at a full scale biocover implemented at Klintholm landfill exhibiting high temperatures. Compost material was collected at Klintholm landfill and incubated with and without CH4 in the laboratory at 10 different temperatures varying between 4 ºC and 70 ºC. The temperature optimum of the methanotrophic community in the biocover material was 45 C. The results indicate that a moderately thermophilic methanotrophic community adapted to the elevated temperature conditions in the biocover had developed. The temperature optimum was comparable to maximum temperatures measured in the deeper parts of the biocover.
