This study shows that bacterial fermentation, not respiration, dominates in upland soils during hypoxia, challenging the assumption that respiration is the primary metabolic strategy.

This study shows that Antarctic soil bacteria can consume trace gases like H2 and CO across wide temperature ranges, with potential increases in activity under future climate scenarios.

The paper investigates chemosynthesis in a marine cave ecosystem, finding that interior communities rely on chemosynthetic processes for carbon fixation and diversity, contrasting with entrance areas.

The paper identifies Flavobacteria in coastal sediments that reduce nitrous oxide emissions by having low substrate affinity, contradicting prior assumptions and suggesting they buffer nitrogen cycling.

This study shows that chemosynthesis significantly contributes to carbon fixation in microbialite ecosystems, enhancing their productivity beyond photosynthesis.

The paper identifies microbial communities in wetland tree barks that mediate methane and hydrogen cycling, showing they can both mitigate and emit climate-active gases.
