Control on rate and pathway of anaerobic organic carbon degradation in the seabed.
TL;DR: It is found that degradation rates transition continuously from the sulfate to the methane zone, thereby demonstrating that terminal steps do not exert feedback control on upstream hydrolytic and fermentative processes, as previously suspected.

Cryptic CH 4 cycling in the sulfate–methane transition of marine sediments apparently mediated by ANME-1 archaea
TL;DR: Analysis of a metagenome-assembled genome suggests that predominant ANME-1 do indeed have the enzymatic potential to catalyze both methane production and consumption, and is consistent with an oxidation of buried organic matter within the SMT.

TL;DR: Investigating microbial life in up to 1.2-kilometer-deep and up to 120°C hot sediments in the Nankai Trough subduction zone found that microbial life decreases as depth and temperature increases down to ∼600 meters below the seafloor, corresponding to temperatures of ∼70°C.

TL;DR: In this paper, the authors analyzed data for sulfate, methane and sulfate reduction from eight sites in Danish coastal waters and found that organic carbon oxidation corresponded to 14-59% of the total sulfate flux into the sulfate-methane transition in subsurface marine sediments where anaerobic oxidation of methane with sulfate takes place.

Methylotrophic methanogenesis fuels cryptic methane cycling in marine surface sediment
Abstract: Methylotrophic methanogenesis is often proposed to be responsible for methane production in sulfate‐rich environments, yet the magnitude of this process remains elusive. In this study, we incubated sediment from Aarhus Bay (Denmark) with 13C labeled CH4 to measure total methane turnover by isotope dilution, and with 14C‐radiotracers to measure specifically the gross hydrogenotrophic and acetoclastic methane production. Highest CH4 production rates (> 200 pmol cm−3 d−1) were found in the top 0–2 cm. Most of this production was via methylotrophic pathways. Methanogenesis via the hydrogenotrophic pathway accounted for less than 20 pmol cm−3 d−1 throughout the surface sediment (0–10 cm), and there was no apparent contribution from acetoclastic methanogenesis. To further assess potentials for methanogenesis from hydrogen, acetate, or trimethylamine (TMA), sediment slurry incuabtions with excess substrate addition were performed. A high and accelarating CH4 production was only detected in incubations amended with TMA. Our results show that methylotrophic methanogenesis dominated the CH4 production in these sulfate‐rich marine surface sediments.
