This study investigates the evolutionary relationships and halophilic adaptations of Nanohaloarchaeota and related DPANN archaea, identifying Caliditerrarchaeota as a new sister group and revealing distinct halophily mechanisms.

This study shows that carbon monoxide exposure promotes growth and activity of carboxydotrophic bacteria in diverse soil ecosystems, suggesting a potential role for soils as a CO sink.

The paper identifies two rumen community types linked to protozoal populations and shows their impact on microbial interactions and metabolite profiles.

The paper investigates reductive dehalogenation in deep-sea cold seeps, identifying diverse RDases and their ecological role in biogeochemical cycles.

This paper demonstrates that the hydrogenase Huc from Mycobacterium smegmatis can drive ATP synthesis from air, providing a traceless energy source for bacterial survival during nutrient starvation.

This study identifies how Mo-CODH and CoxG in Mycobacterium smegmatis oxidize CO and transfer electrons to the respiratory chain via quinone transport.

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

This study isolates two Campylobacterota strains that use molecular hydrogen as an electron donor for dissimilatory nitrate reduction to ammonium, challenging the traditional C:N ratio paradigm.

The paper reconstructs genomes of soil-associated Asgard archaea and uses metatranscriptomics to show their role in carbon compound metabolism relevant to methane production in wetlands.

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.

This study investigates secondary metabolites in cold seep microbiomes using metagenomic, metatranscriptomic, and metabolomic data, revealing diverse biosynthetic gene clusters and their potential ecological roles.

The paper investigates how elevated H2 levels affect microbial communities in upland and wetland soils, finding distinct hydrogenotrophic bacteria stimulated in each environment.

This study identifies mutations in Mycobacterium tuberculosis that confer resistance to nitroimidazole antibiotics, highlighting the need for monitoring these mutations to manage antibiotic use.

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

This study identifies alternative hydrogen uptake pathways in ruminants that reduce methane production by competing with methanogens for hydrogen.
