Novel Alphaproteobacteria transcribe genes for nitric oxide transformation at high levels in a marine oxygen deficient zone

The paper identifies a novel Alphaproteobacteria order, UBA11136, as a major contributor to nitric oxide transformation in marine oxygen deficient zones, revealing new metabolic pathways.

Microbial and Viral Genome and Proteome Nitrogen Demand Varies Across Multiple Spatial Scales Within a Marine Oxygen Minimum Zone

The paper examines how nitrogen availability shapes microbial and viral genome and proteome nitrogen content across spatial scales in a marine oxygen minimum zone.

Microbial metabolism and adaptations in Atribacteria-dominated methane hydrate sediments

The paper investigates microbial metabolism and adaptations in Atribacteria-dominated methane hydrate sediments, identifying key metabolic pathways and stress responses.

Gulf of Mexico blue hole harbors high levels of novel microbial lineages

The paper characterizes microbial communities in a Gulf of Mexico blue hole, revealing novel taxa and metabolic capabilities in hypoxic and anoxic zones.

Novel insights into the taxonomic diversity and molecular mechanisms of bacterial Mn(III) reduction

This paper identifies a novel Betaproteobacterium capable of Mn(III) reduction, expanding the known phylogenetic diversity and revealing new molecular mechanisms for this process.

Phylogenetic and structural diversity of aromatically dense pili from environmental metagenomes

The paper identifies diverse putative e-pilin genes from environmental metagenomes using updated aromatic density thresholds, expanding known e-pili diversity in metal-rich ecosystems.

Feeding rapidly alters microbiome composition and gene transcription in the clownfish gut

This study shows feeding rapidly changes clownfish gut microbiome diversity, gene content, and transcription, with some microbes increasing dramatically post-feeding while others remain stable.

Shifting microbial communities sustain multi-year iron reduction and methanogenesis in ferruginous sediment incubations

This study examines how different Fe(III) oxides affect microbial communities and methane cycling in ferruginous sediments over time, showing that Fe(III) mineralogy influences methanogenesis and iron reduction.
