Mechanisms for the suppression of methane production in peatland soils by a humic substance analog

Abstract

Methane (CH 4) production is often impeded in many northern peatland soils, although inorganic terminal electron acceptors (TEAs) are usually present in low concentrations in these soils. Recent studies suggest that humic substances in wetland soils can be utilized as organic TEAs for anaerobic respiration and may directly inhibit CH 4 pro-5
