Exchange catalysis during anaerobic methanotrophy revealed by 12CH2D2 and 13CH3D in methane

Geochemical Perspectives Letters, 2019
The anaerobic oxidation of methane (AOM) is a crucial component of the methane cycle, but quantifying its role in situ under dynamic environmental conditions remains challenging.

Genome‐Resolved Approach of Guerrero Negro Hypersaline Microbial Mats Reveals the Metabolic Potential of Key Players in a Stratified Community

Environmental Microbiology, Volume 27, Issue 11, November 2025.
The first metagenome‐assembled genomes (MAGs) from Guerrero Negro hypersaline microbial mats were recovered from natural and incubated samples. These MAGs include dominant and rare taxa, whose metabolic potential provides clues to metabolic versatility in the cycling of three elements (carbon, sulfur, and nitrogen) at the genome and community levels ...

Methane concentration and isotopic composition (d13C-CH4) in the Nerja Cave system (South Spain) [PDF]

, 2016
Air in underground caves often has methane (CH4) concentrations below the atmospheric level, due to methanotrophic or other unkown CH4 consuming processes. Caves are thus considered a potential sink for atmospheric methane.

Effects of interactive global changes on methane uptake in an annual grassland. [PDF]

, 2010
The future size of the terrestrial methane (CH4) sink of upland soils remains uncertain, along with potential feedbacks to global warming. Much of the uncertainty lies in our lack of knowledge about potential interactive effects of multiple ...

Treatment of Anaerobic Digester Liquids via Membrane Biofilm Reactors: Simultaneous Aerobic Methanotrophy and Nitrogen Removal

Microorganisms
Anaerobic digestion (AD) produces useful biogas and waste streams with high levels of dissolved methane (CH4) and ammonium (NH4+), among other nutrients.

A Comprehensive Study of Biohopanoid Production in Alphaproteobacteria: Biosynthetic, Chemotaxonomical, and Geobiological Implications

Geobiology, Volume 23, Issue 6, November/December 2025.
ABSTRACT Bacteriohopanepolyol derivatives (BHPDs) and dia‐ and catagenetic products formed from these bacterial membrane modifiers are extensively used as biomarkers in molecular ecological and geoscience studies. Some BHPDs can be assigned to specific phylogenetic bacterial groups. With the vastly increasing availability of complete bacterial genomes,

Climate change induces shifts in coastal Baltic Sea surface water microorganism stress and photosynthesis gene expression

Frontiers in Microbiology
The world’s oceans are challenged by climate change linked warming with typically highly populated coastal areas being particularly susceptible to these effects.

Origin of Sedimentary BHPs Along a Mississippi River–Gulf of Mexico Export Transect: Insights From Spatial and Density Distributions

Frontiers in Marine Science, 2019
We investigated the origin of sedimentary bacteriohopanepolyols (BHPs) in low-density (<1.6 g cm–3), mesodensity (1.6–2.0 and 2.0–2.5 g cm–3) and high-density fractions (>2.5 g cm–3) as well as unfractionated bulk samples in a highly dynamic ...

Origin and temporal variability of unusually low δ13C-DOC values in two High Arctic catchments [PDF]

, 2016
The stable carbon isotopic composition of dissolved organic matter (δ13C-DOC) reveals information about its source and extent of biological processing. Here we report the lowest δ13C-DOC values (−43.8‰) measured to date in surface waters.
