Abstract

In this paper, methane oxidation mechanisms under aerobic and anaerobic conditions in wetlands was introduced. Methane oxidation under aerobic condition occurs at aerobic zone of the wetlands (e.g., rhizosphere and water-sediment interface), which has been studied frequently. Simultaneously, the progress of the three main reactions of anaerobic oxidation of methane (AOM) was systematically reviewed in this paper. Previous studies mostly focus on the sulfate, nitrite, and nitrate dependent AOM processes while iron and manganese driven AOM is still found to be insufficient. The direct microbial interspecies electron transfer (DIET) that influence AOM process had also been reported. This paper also discussed methane emission in wetland and its anaerobic oxidation mechanisms, aiming at providing a theoretical basis for the study of methane oxidation and new ideas for methane emission reduction in wetlands.

Key words： wetland methane emission anaerobic oxidation of methane
