Snapshot of methanogen sensitivity to temperature in Zoige wetland from Tibetan plateau

Frontiers in Microbiology, 2015
Zoige wetland in Tibetan plateau represents a cold environment at high altitude where significant methane emission has been observed. However, it remains unknown how the production and emission of CH4 from Zoige wetland will respond to a warming climate.

Relating Methanogen Community Structure and Anaerobic Digester Function [PDF]

, 2015
Much remains unknown about the relationships between microbial community structure and anaerobic digester function. However, knowledge of links between community structure and function, such as specific methanogenic activity (SMA) and COD removal rate ...

Bridging the Gap From Peat to Ponds: Terrestrial and Aquatic Greenhouse Gas Emissions in an Evolving Permafrost‐Associated Subarctic Peatland

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Rapid permafrost thaw in peatlands transforms the subarctic landscape into a mosaic of ponds and peat soil, varying in moisture, carbon and nutrients, and time since thaw. As subarctic permafrost degrades, ponds emerge and mature and can gradually infill with Sphagnum peat.

Hopanoid lipids may facilitate aerobic nitrogen fixation in the ocean. [PDF]

, 2019
Cyanobacterial diazotrophs are considered to be the most important source of fixed N2 in the open ocean. Biological N2 fixation is catalyzed by the extremely O2-sensitive nitrogenase enzyme.

Mechanistic Modeling of Microtopographic Impacts on CO2 and CH4 Fluxes in an Alaskan Tundra Ecosystem Using the CLM-Microbe Model [PDF]

, 2019
Spatial heterogeneities in soil hydrology have been confirmed as a key control on CO2 and CH4 fluxes in the Arctic tundra ecosystem. In this study, we applied a mechanistic ecosystem model, CLM-Microbe, to examine the microtopographic impacts on CO2 and ...

Impact of Fire and Heat Stress on Soil Microorganisms: A Review of Community Changes, Molecular Responses and Plant‐Beneficial Roles

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This work reviewed the direct and indirect effects of fires on microbial communities and the resilience strategies microbes use to withstand high temperatures . ABSTRACT Fire, whether occurring on the surface or underground, significantly influences soil microbial dynamics by reshaping community composition, functional diversity and overall soil and ...

Soil Microbiome of Tropical Seasonal and Permanent Small Wetlands

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Distinct hydrological regimes shape microbial communities and metabolic pathways in tropical wetlands. Redox‐driven shifts highlight enhanced methanogenesis under anoxia, and dominant archaeal and bacterial groups reflect specific redox conditions and adaptations, with important implications for biogeochemical cycling and climate‐relevant processes ...

Extracellular electron transfer based methylotrophic methanogenesis in paddy soil and the prevalent Methanomassiliicoccus

Communications Earth & Environment
The biogenic methane contributes obviously to global warming, and direct interspecies electron transfer (DIET) driven CO2 reductive methanogenesis is one of the important methanogenic pathways.

Effect of Dissimilatory Iron Reduction on the Reduction of CH4 Production in Landfill Conditions

Journal of Chemistry, 2019
A high solid anaerobic incubation system was used to study the effect of dissimilatory iron reduction on the inhibition of methanogenesis in a landfill. Different iron sources including FeC6H5O7, Fe2(SO4)3, Fe2O3, and Fe0 were studied. The different iron

Spatial Patterns and Overlap of Sedimentary and Rhizosphere Microbiomes of the Seagrass Zostera capensis

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Sedimentary microbiomes and, for the first time, rhizosphere microbiomes of Zostera capensis, South Africa's most abundant seagrass, were characterised using 16S rRNA metabarcoding across three estuaries. After accounting for seawater‐derived microbes, we found that sediment and rhizosphere communities largely overlapped but also harbor distinct core ...
