Limnology and Oceanography, Volume 71, Issue 7, July 2026.Abstract Numerous abandoned wells in the North Sea may provide gas, particularly methane (CH4), migration pathways by penetrating shallow, biogenic gas accumulations. However, related sampling campaigns have been largely contradictory and lack a substantial database. Research cruise MSM98 targeted the abandoned wells B18‐1, DOK 1‐X, B11‐2, THOR and D‐1

Free-Living Protozoa with Endosymbiotic Methanogens
, 2018 Methanogenic bacteria occur in many, but not all, free-living obligate anaerobic protozoa. This sort of symbiosis is especially common among anaerobic ciliates but is also found in a few species of amoebae and flagellates. Protozoa harbouring methanogens

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.Abstract Drainage canals are potential hotspots of methane (CH4) emissions from degraded peatlands in Southeast Asia. Estimates of CH4 emissions from these canals remain scarce, and both the temporal variability and pathways of CH4 emissions are uncertain.

Ammonia inhibition on thermophilic aceticlastic methanogens
, 2002 The inhibition effects of total ammonia nitrogen (TAN) on aceticlastic methanogenic activity using biomass from thermophilic anaerobic reactors were investigated in this study.

Digestive tract methanodrome: Physiological roles of human microbiota-associated methanogens
, 2020 Methanogens are the archaea most commonly found in humans, in particular in the digestive tract and are an integral part of the digestive microbiota.

Protein Science, Volume 35, Issue 7, July 2026.Abstract Hydrogenotrophic methanogens are anaerobic archaea that convert carbon dioxide and hydrogen into methane. Central to this process is the heterodisulfide reductase (Hdr), which catalyzes the reduction of the heterodisulfide made of coenzyme M and coenzyme B. In vivo, Hdr functions in association with electron‐donating modules such as the [NiFe]‐

, 2012 This study aims to investigate thermophilic methanogens in turf used as an inoculum. Results showed that Methanoculleus sp. regarded as hydrogenotrophic and Methanosarcina sp. regarded as acetoclastic methanogens were present in turf tested.

Non-autotrophic methanogens dominate in anaerobic digesters
, 2017 Anaerobic digesters are man-made habitats for fermentative and methanogenic microbes, and are characterized by extremely high concentrations of organics. However, little is known about how microbes adapt to such habitats.

Diversity and Functional Analysis of the FeMo-Cofactor Maturase NifB
Frontiers in Plant Science, 2017 One of the main hurdles to engineer nitrogenase in a non-diazotrophic host is achieving NifB activity. NifB is an extremely unstable and oxygen sensitive protein that catalyzes a low-potential SAM-radical dependent reaction.
