Freshwater wetlands and coastal sediments are becoming hotspots for the emission of greenhouse gas methane. Eutrophication-induced deposition organic matter leads to elevated methanogenesis sulfate reduction, thereby increasing concentrations methane toxic sulfide, respectively. However, effects sulfide stress on anaerobic methanotrophic biofilter have not been well explored.

Short synopsis statement This study investigated archaea responded revealing transient inhibition physiological adaptation mechanisms.
