Sulfate-catalyzed denitrifying anaerobic methane oxidation process mediated by Methanobacterium sp. from digestion sludges.
The reversibility of methanogenesis suggests a broader ecological role for methanogens beyond methane production. However, the mechanisms of reverse methanogenesis in methanogens remain elusive, particularly in aquatic ecosystems with coexisting sulfate and nitrate. Here, a 423-day enrichment in a methane-fed bioreacto...
