Atmospheric hydrogen oxidation extends to the domain archaea

This study shows that archaea, like bacteria, oxidize atmospheric hydrogen and carbon monoxide, revealing a cross-domain metabolic trait with ecological and evolutionary significance.

Molecular hydrogen is an overlooked energy source for marine bacteria

This study shows marine bacteria consume molecular hydrogen as an energy source, with H2 oxidation more active in subantarctic waters and supported by genomic and experimental evidence.

A nitrite-oxidizing bacterium constitutively consumes atmospheric hydrogen

This study shows Nitrospira moscoviensis oxidizes atmospheric hydrogen using a high-affinity hydrogenase, enhancing its growth and survival under varying nitrite conditions.

Metabolic flexibility allows generalist bacteria to become dominant in a frequently disturbed ecosystem

This study shows that metabolically flexible bacteria dominate in disturbed ecosystems, outcompeting specialists during habitat disturbance.

BonA from Acinetobacter baumannii forms a divisome-localized decamer that supports outer envelope function

This study identifies BonA as an outer membrane protein in Acinetobacter baumannii that forms a transient decamer, supports outer envelope function, and is involved in cell division and motility.

A genome compendium reveals diverse metabolic adaptations of Antarctic soil microorganisms

This study identifies diverse metabolic adaptations of Antarctic soil microorganisms using metagenomic analysis and experimental validation.

Carbon monoxide dehydrogenases enhance bacterial survival by oxidising atmospheric CO

This study shows that carbon monoxide dehydrogenases enhance bacterial survival by providing a supplemental energy source during organic carbon starvation.
