Microbial methanogenesis in the sulfate-reducing zone of sediments in the Eckernförde Bay, SW Baltic Sea [PDF]
Biogeosciences, 2018 Benthic microbial methanogenesis is a known source of methane in marine systems. In most sediments, the majority of methanogenesis is located below the sulfate-reducing zone, as sulfate reducers outcompete methanogens for the major substrates hydrogen

Active methylotrophic methanogenesis by a microbial consortium enriched from a terrestrial meteorite impact crater [PDF]
mBioMicrobial methane generation (methanogenesis) is an important metabolic process in the terrestrial deep biosphere and is an analog to early Earth as it is proposed to be one of the most ancient metabolisms on Earth.

Magnetite drives microbial community restructuring and stimulates aceticlastic methanogenesis of type II Methanosarcina in mangrove sediments [PDF]
MicrobiomeBackground Mangrove wetlands are critical hotspots of methane emissions, yet the role of naturally occurring minerals in shaping their microbial communities and methanogenic processes is poorly understood.

Coexistence of methanogenesis and sulfate reduction in a sulfate-adapted enrichment culture from an oil reservoir [PDF]
Applied and Environmental MicrobiologyOil reservoirs are complex ecosystems where microorganisms play a vital role in hydrocarbon degradation, mostly with methanogenesis as the terminal electron-accepting process. Especially in offshore oil reservoirs, sulfate-containing seawater is injected

Mer overexpression in Methanosarcina acetivorans affects growth and methanogenesis during substrate adaptation [PDF]
Applied and Environmental MicrobiologyEvidence suggests that multienzyme complexes are involved in biological methane production (methanogenesis), although the composition of the Wolfe Cycle methanogenesis complexes may vary between diverse methanoarchaeal taxa ...

Thermodynamic method for analyzing and optimizing pretreatment/anaerobic digestion systems [PDF]
Biofuel Research Journal, 2023 This paper builds a quantitative thermodynamic model for the microbial hydrolysis process (MHP, which uses Caldicellulosiruptor bescii at 75°C for pre-digestion) for producing biogas from a 5-10% aqueous suspension of dairy manure (naturally buffered ...

A variety of substrates for methanogenesis
Case Studies in Chemical and Environmental Engineering, 2023 The number of methanogenesis substrates known to date has increased more than six-fold since the late 80s, bringing to 152 the number of proven substrates for methanogenesis, plus 41 putative substrates predicted on the basis of ‘omic’ and biochemical ...

Frontiers in Microbiology, 2023 IntroductionAnaerobic oxidation of methane (AOM) is hypothesized to occur through reverse hydrogenotrophic methanogenesis in marine sediments because sulfate reducers pull hydrogen concentrations so low that reverse hydrogenotrophic methanogenesis is ...

Microbial methane formation in deep aquifers associated with the sediment burial history at a coastal site [PDF]
Biogeosciences, 2023 Elucidating the mechanisms underlying microbial methane formation in subsurface environments is essential to understanding the global carbon cycle. This study examined how microbial methane formation (i.e., methanogenesis) occurs in natural-gas-bearing ...
