Land use effects on soil microbiome composition and traits with consequences for its ecosystem carbon use efficiency

The paper investigates how land use intensity affects soil microbiome traits and carbon use efficiency (CUE) through metaproteomics and decomposition experiments, showing opposing effects in low and high pH soils.

Differential contribution of nitrifying prokaryotes to groundwater nitrification

The paper investigates the contribution of nitrifying prokaryotes to groundwater nitrification, finding that AOB dominate the first step of nitrification despite CMX's numerical predominance.

Mycelial nutrient transfer promotes bacterial co-metabolic organochlorine pesticide degradation in nutrient-deprived environments.

This study shows that fungal mycelia transfer nutrients to bacteria, enhancing co-metabolic degradation of organochlorine pesticides in nutrient-poor environments.

Neonatal Peyer's patch cDC activation as a pacemaker of postnatal immune maturation

This study identifies neonatal Peyer's patch mononuclear phagocytes as a key driver of postnatal immune maturation and shows that targeted interventions can modulate mucosal immune responses.

Database-independent analysis of probable post-translational modifications of soil proteins across ecosystems

The paper uses a database-independent method to identify probable post-translational modifications in soil proteins across different ecosystems, finding similar PTMs across ecosystems but significant changes in some mass intervals.

Oxygen production by an ammonia-oxidizing archaeon

This study shows that the ammonia-oxidizing archaeon Nitrosopumilus maritimus produces oxygen and dinitrogen in the dark, challenging previous assumptions about its metabolic role in oxygen-depleted environments.

Critical Assessment of Metaproteome Investigation (CAMPI): a Multi-Lab Comparison of Established Workflows

CAMPI evaluates metaproteomic workflows across labs, finding sample processing drives peptide variability while workflows yield similar functional profiles.

Bolstering fitness via opportunistic CO2 fixation: mixotroph dominance in modern groundwater

The paper uses stable isotope cluster analysis to show mixotrophs, not obligate chemolithoautotrophs, dominate carbon cycling in groundwater by opportunistically using both organic and inorganic carbon sources.

Interspecies metabolite transfer and aggregate formation in a co-culture of Dehalococcoides and Sulfurospirillum dehalogenating tetrachloroethene to ethene

This study co-cultures Dehalococcoides and Sulfurospirillum to dehalogenate tetrachloroethene to ethene, showing enhanced rates and cofactor production by S. multivorans for D. mccartyi.

Ecology and Function of Bacterial Lipases within the Gut Microbiome

This study identifies microbial lipases in the gut microbiomes of mice, pigs, and humans, revealing their role in triglyceride metabolism through glycerol utilization.

Explorative meta-analysis of 417 extant archaeal genomes to predict their contribution to the total microbiome functionality

The paper predicts archaea's contribution to global microbiome functionality by analyzing 417 archaeal genomes and finding functional redundancy patterns.

The total fungal microbiome functionality

The paper predicts the total fungal microbiome functionality using 377 annotated fungal genomes, finding 42.4 million functions with only 0.06% known, highlighting the need for new methods to explore rare functions.
