Profiling trace organic chemical biotransformation genes, enzymes and associated bacteria in microbial model communities

The paper investigates biotransformation of trace organic chemicals by microbial communities, identifying key genes, enzymes, and bacteria involved in their degradation.

Bacterial ecology and evolution converge on seasonal and decadal scales

The paper analyzes a two-decade freshwater lake metagenome dataset to show that ecological and evolutionary processes in microbial communities operate on seasonal and decadal scales.

Geographic population structure and distinct population dynamics of globally abundant freshwater bacteria

The paper examines geographic population structure and dynamics of freshwater bacteria using metagenomes and genomes, finding significant spatial differentiation and contrasting population dynamics across species.

Network analysis uncovers associations in the turnover of C1 molecules in a winter lake

The paper uses network analysis to study C1 molecule turnover in an ice-covered lake, revealing both known and novel microbial associations and an upward carbon flow under cold low-light conditions.

Linking prokaryotic genome size variation to metabolic potential and environment

The paper links prokaryotic genome size variation to metabolic potential and environmental factors in the Baltic Sea.

Genomics of viruses infecting green and purple sulfur bacteria in two euxinic lakes

The paper identifies viral genomes infecting green and purple sulfur bacteria in euxinic lakes and finds they carry genes involved in metabolic processes similar to those in Cyanobacteria.

Taxonomic and functional diversity of aquatic heterotrophs is sustained by dissolved organic matter chemodiversity

The paper investigates how dissolved organic matter (DOM) chemodiversity sustains taxonomic and functional diversity of aquatic heterotrophs across different model communities.

Biogenic methane cycling is controlled by microbial cohorts

The paper identifies new microbial players in methane cycling by combining network analysis with cultivated model communities from a lake time-series.

Comprehensive analysis of chemical and biological problems associated with browning agents used in aquatic studies

This study compares the chemical and biological impacts of three browning agents on aquatic systems, finding that leonardite products have distinct effects compared to terrestrial-derived DOM.

A genomic perspective on genome size distribution across Earth's microbiomes reveals a tendency to gene loss

The paper analyzes genome size distribution across Earth's microbiomes and finds that environmental microorganisms have smaller genomes than lab-cultivated ones, with ecological and phylogenetic factors influencing genome size.

Comprehensive dataset of shotgun metagenomes from stratified freshwater lakes and ponds

The paper presents a comprehensive dataset of 267 shotgun metagenomes from 41 stratified freshwater lakes and ponds to study microbial communities and their role in carbon cycling.

Freshwater Chlorobia exhibit metabolic specialization among cosmopolitan and endemic populations

The paper analyzes global metagenomes to study metabolic specialization of freshwater Chlorobia, revealing widespread distribution and niche-specific adaptations.

Streamlined freshwater bacterioplankton Nanopelagicales (acI) and Ca. Fonsibacter (LD12) thrive in functional cohorts

The paper investigates cooperation strategies in freshwater bacterioplankton, showing how different microbial genera thrive through ecotype or community-level interactions.

Decreased snow cover stimulates under ice primary producers, but impairs methanotrophic capacity

The paper shows that reduced snow cover increases light penetration, boosting primary production but reducing methanotrophic activity, leading to higher methane emissions.

Contrasting patterns of genome-level diversity across distinct co-occurring bacterial populations

The paper examines genetic and ecological differentiation in freshwater bacterial populations using single-cell genomes and metagenomic data, finding ecologically distinct populations within some lineages but not others.

Metabolic Network Analysis and Metatranscriptomics Reveals Auxotrophies and Nutrient Sources of the Cosmopolitan Freshwater Microbial Lineage acI

Model communities hint to promiscuous metabolic linkages between ubiquitous free-living freshwater bacteria

The paper investigates metabolic interactions among free-living freshwater bacteria and finds they form loose, unspecific cooperative networks rather than specific dependencies.
