A comparison of sequencing of complex mock communities performed at multiple depths and analysed using different methods establishes minimum standards that can ensure the accuracy of metagenomic analy...

Experimental increases in CO2 stimulated plant growth are facilitated by re-distributed root systems to extract nutrient resources more efficiently

A new study from the research group of Barbara Bayer at DOME | CeMESS discovered that the two Austrian lakes Mondsee and Attersee are a source of methane throughout the year. The study was recently pu...

In addition to diet and medication, transmission between people can also play an important role in the microbiome

Abstract. Symbiotic associations between microorganisms often involve eukaryotes partnering with microbes for nutrient exchange, protection, and resource a

Microorganisms drive the global sulfur cycle, but the complexity of sulfur redox transformations complicates understanding of their evolution, metabolism, and ecology. We developed DiSuCy, a manually ...

Microorganisms have long driven Earth’s oxidative sulfuric cycle using complex sulfur-oxidizing systems. This study shows that this molecular machinery first originated in the anoxic Archean eon and g...

Escherichia coli is widespread in healthy breastfed infants, yet its ecological role is unclear. Here, the authors provide insights into the mechanisms supporting its persistence and co-existence with...

Rumen microbiota are essential for cattle husbandry, providing energy and protein through fermentation. However, this symbiotic process also produces methane as a byproduct, representing both a loss of feed energy for the animal and a major source of greenhouse gas emissions. A new study now uncovers the identity and metabolism of rumen bacteria that degrade a ubiquitous plant- and algae-derived sulfosugar, revealing a previously unrecognized process that may help limit methane production.

Abstract. Sulfoquinovose, a sulfonated sugar derived from the thylakoid membrane lipid sulfoquinovosyl diacylglycerol, is abundant in photosynthetic organi

By characterizing the structure and function of a methylthio-alkane reductase system, researchers could open avenues for using bacteria to produce ethylene and more.

Isolation and characterization of a novel North Sea ammonia oxidizing archaeon, Nitrosarchaeum marinum T12, reveals an adaptation to a broad salinity under

Without key cell cycle control genes, SAR11 cells experience aneuploidy and growth inhibition when exposed to changes in nutrients, carbon sources or temperature stress, a vulnerability that may repre...

A metagenomic survey of babies attending the first year of nursery detected extensive baby-to-baby microbial strain transmission, pointing to social interactions in infancy as crucial drivers of infan...

This study provides valuable insights into the intricate relationship between gut microbiota and host personality traits, using captive common marmosets as a model. By controlling for diet and housing conditions, it probes key host factors such as personality, age, sex, and social group membership, offering a robust framework for understanding microbiome-host interactions. The discovery of specific microbial taxa associated with personality traits, particularly the enrichment of sulfite-reducing genera in more avoidant individuals, underscores the potential of the gut microbiome to reflect or be associated with personality differences. These findings advance our understanding of microbiome-host dynamics and pave the way for future research on the mechanistic links between behavior and gut microbiota in other animal models and across broader ecological contexts.

Surprise discovery could pave the way for new treatments against drug-resistant infections.

The bacterial ubiquitin ligase NleL evades host defence mechanisms both by inhibiting pyroptosis and by preventing infected intestinal epithelial cells from being extruded into the lumen and expelled ...

An approach combining BONCAT, stable isotope probing and metaproteomics showcases the hidden metabolic interconnectivity of microorganisms within an anaerobic digestion community.

Abstract. The Genome Taxonomy Database (GTDB; https://gtdb.ecogenomic.org) provides a phylogenetically consistent and rank normalized genome-based taxonomy

Ein Teelöffel voll Schlamm vom Meeresgrund enthält rund eine Milliarde Bakterien, Tausende verschiedener Arten. Kaum bekannt, aber faszinierend und wichtig für den Kohlenstoffkreislauf der Erde. Ein ...

Warum macht man eigentlich Feldforschung in Kanada? Was treibt uns Forscher*innen dazu, mit Bären- und Mosquitospray bewaffnet, bei jedem Wetter in Wäldern oder Mooren zu graben? Warum nehmen wir schm...

A species of bacteria grows when both ferrihydrite and sulfide are present, but not when either is absent.

Human activities are driving rapid environmental change on a global scale, with pollutants playing a critical role in pushing planetary systems beyond safe limits. These changes have profound conseque...

Soil ecosystems form the foundation of planetary health and play a critical role in climate feedback mechanisms. However, they are also vulnerable to the impacts of global change.
