Iron mineral dissolution releases iron and associated organic carbon during permafrost thaw

Nature Communications, 2020
Iron minerals trap carbon in permafrost, preventing microbial degradation and release to the atmosphere as CO2, but the stability of this carbon as permafrost thaws is unclear.

CANT-HYD: A Curated Database of Phylogeny-Derived Hidden Markov Models for Annotation of Marker Genes Involved in Hydrocarbon Degradation

Frontiers in Microbiology, 2022
Many pathways for hydrocarbon degradation have been discovered, yet there are no dedicated tools to identify and predict the hydrocarbon degradation potential of microbial genomes and metagenomes.

Microbial diversity and biogeochemical interactions in the seismically active and CO2- rich Eger Rift ecosystem

Environmental Microbiome
The Eger Rift subsurface is characterized by frequent seismic activity and consistently high CO2 concentrations, making it a unique deep biosphere ecosystem and a suitable site to study the interactions between volcanism, tectonics, and microbiological ...

Global patterns in culturable soil yeast diversity

iScience, 2021
Summary: Yeasts, broadly defined as unicellular fungi, fulfill essential roles in soil ecosystems as decomposers and nutrition sources for fellow soil-dwellers. Broad-scale investigations of soil yeasts pose a methodological challenge as metagenomics are

Microbial Populations of Stony Meteorites: Substrate Controls on First Colonizers

Frontiers in Microbiology, 2017
Finding fresh, sterilized rocks provides ecologists with a clean slate to test ideas about first colonization and the evolution of soils de novo. Lava has been used previously in first colonizer studies due to the sterilizing heat required for its ...

High latitude terrestrial carbon isotope and mercury perturbations across the Late Triassic Carnian Pluvial Episode in Northwestern China

Scientific Reports
The Carnian Pluvial Episode (CPE) was a Late Triassic interval of global environmental changes and biological turnovers linked to C-cycle perturbation and global warming.

Growth of candidate phyla radiation bacteria in groundwater incubations reveals widespread adaptations to oxic conditions

Microbiome
Background The candidate phyla radiation (CPR) comprises a widespread but poorly understood group of bacteria with limited cultured representatives, largely due to their metabolic dependencies on microbial hosts.
