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 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.

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.

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 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.
