Soil microbial community response to corrinoids is shaped by a natural reservoir of vitamin B12.

The paper investigates how corrinoid structure affects soil microbial community composition and stability through experimental and genomic analysis.

Phylogenetic distribution and experimental characterization of corrinoid production and dependence in soil bacterial isolates

The paper investigates corrinoid production and dependence in soil bacteria to understand metabolic interactions, finding metabolic compatibility and conserved traits across genera.

A subset of viruses thrives following microbial resuscitation during rewetting of a seasonally dry California grassland soil

The paper investigates virus-host dynamics in soil following rewetting, finding that a subset of viruses thrive and drive microbial lysis, contributing to CO2 efflux.

Functional succession of actively growing soil microorganisms during rewetting is shaped by precipitation history

The paper investigates how precipitation history affects microbial succession in rewetted soils by analyzing functional traits and gene abundance over time.

Methane-derived carbon flow through host-virus trophic networks in soil

This study identifies active host-virus interactions in methane-fueled soil microbial networks by tracing carbon transfer from hosts to viruses.

Identification of a novel cobamide remodeling enzyme in the beneficial human gut bacterium Akkermansia muciniphila

This paper identifies a novel cobamide remodeling enzyme, CbiR, in Akkermansia muciniphila that enables the bacterium to use diverse cobamides by modifying their structure.

Unexpected diversity of CPR bacteria and nanoarchaea in the rare biosphere of rhizosphere-associated grassland soil

The paper identifies unexpected diversity of CPR bacteria and nanoarchaea in grassland soil by analyzing particles less than 0.2 m, revealing new taxa and potential adaptations to aerobic conditions.
