The paper improves 16S rRNA gene primers to better detect Patescibacteria in wastewater treatment plants, revealing their global diversity and potential ecological roles.

Taurine as a key intermediate for host-symbiont interaction in the tropical sponge Ianthella basta

The paper shows that taurine is a key intermediate in the metabolic exchange between the sponge Ianthella basta and its microbial symbionts, supporting sulfur cycling and nutrient transfer.

Ammonia-oxidizing archaea possess a wide range of cellular ammonia affinities

The paper determines ammonia oxidation kinetic properties of 12 AOA strains, finding they have a wide range of substrate affinities, challenging previous assumptions about their uniformity.

A novel oxidase from Alcaligenes sp. HO-1 oxidizes hydroxylamine to N2

This study identifies a novel oxidase in Alcaligenes sp. HO-1 that converts hydroxylamine to N2, revealing a previously unknown enzymatic pathway for nitrogen cycling.

Exploring the upper pH limits of nitrite oxidation: diversity, ecophysiology, and adaptive traits of haloalkalitolerant Nitrospira

This study identifies haloalkalitolerant Nitrospira species in extreme pH lakes, revealing their diversity and adaptive traits for nitrite oxidation at high pH.

Genomic and kinetic analysis of novel Nitrospinae enriched by cell sorting

The paper isolates and characterizes two new Nitrospinae genera from marine environments, revealing differences in nitrite affinity and metabolic capabilities.

Glacial runoff promotes deep burial of sulfur cycling-associated microorganisms in marine sediments

This study shows that glacial runoff increases sedimentation rates, promoting the deep burial of sulfur-cycling microorganisms in marine sediments.

DNA-foraging bacteria in the seafloor

This study identifies DNA-foraging bacteria in marine sediments and shows they degrade and recycle DNA, contributing to nutrient cycling in the seafloor.

Characterization of a thaumarchaeal symbiont that drives incomplete nitrification in the tropical sponge Ianthella basta

This paper characterizes a thaumarchaeal symbiont in the sponge Ianthella basta, showing it is the sole ammonia-oxidizer and reveals adaptations for a mixotrophic lifestyle.

Peatland Acidobacteria with a dissimilatory sulfur metabolism

The paper identifies novel Acidobacteria in peatlands with sulfur metabolism capabilities, including both sulfate respiration and sulfur oxidation, and highlights their ecological roles in organic matter decomposition.

AmoA-targeted polymerase chain reaction primers for the specific detection and quantification of comammox Nitrospira in the environment

The paper develops PCR primers specifically targeting comammox Nitrospira amoA genes, enabling their detection and quantification in diverse environments with high specificity and sensitivity.
