This study shows ANME-2a archaea use multiple electron acceptors for methane oxidation in brackish coastal sediments, with highest activity below the sulfate-methane transition zone.

The paper examines how oxygen and sulfide affect microbial N2O production and consumption in coastal sediments under seasonal redox changes, finding that sulfide can enhance or inhibit N2O consumption depending on concentration.

The paper investigates the genomic potential and ecophysiology of ANME-2a for metal-dependent anaerobic methane oxidation in coastal sediments, identifying two clusters with differing electron transfer capabilities.

This study examines how verrucomicrobial methanotrophs adapt to heat and acidity by analyzing membrane fatty acid composition and genomic responses across different strains.

The paper investigates microbial methane cycling in eutrophic coastal sediments, finding that methanogenesis dominates over methanotrophy and that a diverse methanogenic community drives methane production.

This study investigates the clumped isotope signatures of different methanogenic pathways and identifies factors influencing methane isotope compositions.

This study investigates the metabolic flexibility of Ca. Methanoperedens and its interactions with sulfate-reducing bacteria in Lake Cadagno sediments using metagenomics and incubations.

The paper examines nitrogen cycling in sediments of a seasonally euxinic coastal ecosystem, finding high nitrogen removal potential through denitrification and DNRA.

The paper examines nitrogen dynamics in coastal waters with varying redox conditions, finding that long-term euxinia reduces ammonium removal by inhibiting nitrification.

The paper examines seasonal nitrification dynamics in marine Lake Grevelingen, finding limited nitrification's role in ammonium removal due to stratification and low nitrifier abundance.

The paper identifies and characterizes mini-bacterioferritin, a novel ferritin-like protein from an anaerobic methane-oxidizing archaeon, revealing its structure and evolutionary relationships.

This study examines how freshwater anaerobic methanotrophic archaea respond to sulfide exposure, showing transient inhibition and physiological adaptation mechanisms.

The paper examines seasonal changes in methane oxidation by microbial communities in a coastal basin, finding that methane removal remains active even in anoxic conditions, but is reduced during periods of weakened stratification.

This study develops a novel mesocosm setup to measure methane emissions from submerged peat mosses and finds that methanotrophs significantly reduce methane emissions.

The paper compares bacterial and methanotrophic diversity between an Italian paddy field and adjacent meadow, finding distinct microbial communities but no significant CH4 flux differences.

The paper examines microbial diversity and nitrogen cycling in Citarum River sediment along a pollution gradient, finding reduced diversity and shifts in microbial phyla with increased pollution.

The paper evaluates genomic signatures for metagenomics, finding that Chargaff’s second parity rule reduces strand dependence and introduces two novel signatures that improve performance.
