An influence of methane concentration on the methanotrophic activity of a model landfill cover

Evaluation of kinetic parameters of methane oxidation under various conditions, on the basis of an analysis of the literature and the authors' own laboratory research, is presented. Variation in methanotrophic activity in the profile of a simulated landfill cover was observed. The greatest activity was found at a depth of 60 cm. A low affinity (1/KM) and high potential activity (Vmax) were observed. Vmax values ranged from 0.11 × 10−3 to 0.86 × 10−3 units. The values of KM ranged from 0.6 to 2.9% of CH4 (v/v).
