Anaerobic methanotrophic archaea of the ANME-2d clade feature lipid composition that differs from other ANME archaea. [PDF]

open access: yesFEMS Microbiology Ecology, 2019
ABSTRACT The anaerobic oxidation of methane (AOM) is a microbial process present in marine and freshwater environments. AOM is important for reducing the emission of the second most important greenhouse gas methane. In marine environments anaerobic methanotrophic archaea (ANME) are involved in sulfate-reducing AOM.

Immunological Localization of Coenzyme M Reductase in Anaerobic Methane-Oxidizing Archaea of ANME 1 and ANME 2 Type

open access: yesGeomicrobiology Journal, 2008
The Black Sea is a large, euxinic marine basin, in which the anaerobic oxidation of methane (AOM) plays an important role in the carbon cycle. Methane-related carbonate build-ups, found on the NW' Black Sea shelf are part of an unique microbial ecosystem.

On the behaviour of the ANM continuation in the presence of bifurcations [PDF]

open access: yesCommunications in Numerical Methods in Engineering, 2003
AbstractThe asymptotic‐numerical method (ANM) is a path following technique which is based on high order power series expansions. In this paper, we analyse its behaviour when it is applied to the continuation of a branch with bifurcation points. We show that when the starting point of the continuation is near a bifurcation, the radius of convergence of

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

open access: yesJournal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Carbonate‐Associated Sulfate Does Not Record Superheavy δ34S in Deep Scandinavian Bedrock Fractures: Implications for Pyrite Formation in the Deep Biosphere

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract In deep bedrock fractures of the Fennoscandian shield, pyrite with “superheavy” δ34S values of up to 147‰ exists together with calcite. The extreme variability and 34S‐enrichment in pyrite indicate that microbial sulfate reduction (MSR) evolved to almost complete sulfate exhaustion in closed‐system microenvironments.

Putative Mechanisms for Initial Reaction of Anaerobic Benzene Degradation Presumably Involving a Flavoprotein

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Anaerobic biodegradation of benzene by sulphate‐reducing strain BzS1 was studied by combining genomics, differential proteomics and targeted metabolite analyses. Strain BzS1 has an exceptionally streamlined metabolism. A highly abundant heterotrimeric flavoprotein may add benzene to either enolpyruvate or glutaconyl‐CoA followed by channelling into the

Beyond Continuity: A Binary‐Outcome Cross‐Lagged Panel Model of Ikigai and Social Interaction Among Community‐Dwelling Older Adults

open access: yesGeriatrics &Gerontology International, Volume 26, Issue 8, August 2026.
Using a binary‐outcome cross‐lagged panel model, this study examines the longitudinal association between social interaction and Ikigai among Japanese older adults. Richer social interaction predicted subsequent Ikigai, whereas the reverse pathway did not reach conventional statistical significance in the cross‐lagged model, highlighting the potential ...

Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs).

Different Ferromanganese Concretion Morphologies Host Distinct Microbial Communities and Metal Accumulation Patterns in the Baltic Sea

open access: yesEnvironmental Microbiology, Volume 28, Issue 7, July 2026.
We investigated how microbes influence the metal accumulation and release in Fe‐Mn concretions from the Gulf of Finland using microcosm incubation experiments. We studied three main concretion morphotypes: crust, discoidal, and spheroidal. Microbes enhanced metal accumulation in discoidal and spheroidal morphotypes.
