Graminoids Increase Greenhouse Gas Emissions From Thawed Permafrost at the End of the Growing Season

Global Change Biology, Volume 32, Issue 3, March 2026.
Field study investigating whether and to which degree graminoids further reduce soil redox and lead to more greenhouse gas emissions from thawing permafrost soil on top of hydrology and anoxia effects. Graminoids, thus, contribute to thawed permafrost soils turning to C sources rather than sinks toward the end of the growing season.

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]

, 2009
A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

The bacteriohopanepolyol inventory of novel aerobic methane oxidising bacteria reveals new biomarker signatures of aerobic methanotrophy in marine systems [PDF]

, 2016
Aerobic methane oxidation (AMO) is one of the primary biologic pathways regulating the amount of methane (CH4) released into the environment. AMO acts as a sink of CH4, converting it into carbon dioxide before it reaches the atmosphere. It is of interest

Particulate methane monooxygenase genes in methanotrophs [PDF]

Journal of Bacteriology, 1995
A 45-kDa membrane polypeptide that is associated with activity of the particulate methane monooxygenase (pMMO) has been purified from three methanotrophic bacteria, and the N-terminal amino acid sequence was found to be identical in 17 of 20 positions for all three polypeptides and identical in 14 of 20 positions for the N terminus of AmoB, the 43-kDa ...

Fostering Peat Moss Feedbacks to Accelerate Peatland Restoration

Global Change Biology, Volume 32, Issue 3, March 2026.
Alternative stable states and peat moss and vascular plant feedbacks in peatlands. Selected feedbacks in a peat moss‐dominated state or a vascular plant‐dominated state. The two insets show ecosystem states (dot) in resilience landscapes (bottom).

Activity and abundance of methane-oxidizing bacteria in secondary forest and manioc plantations of Amazonian Dark Earth and their adjacent soils

Frontiers in Microbiology, 2014
The oxidation of atmospheric CH4 in upland soils is mostly mediated by uncultivated groups of microorganisms that have been identified solely by molecular markers, such as the sequence of the pmoA gene encoding the β-subunit of the particulate methane ...

Increased CH4 Oxidation in Arctic Tundra Ecosystems Caused by Vegetation‐Mediated Soil Drying

Global Change Biology, Volume 32, Issue 3, March 2026.
In a warmer Arctic, vegetation changes can play a critical role in methane dynamics. Our results indicate that taller vegetation, shifts in species composition, and warmer air temperatures enhance soil aeration by increasing evapotranspiration, thereby promoting methane oxidation in surface soils.

Methane and microbial dynamics in the Gulf of Mexico water column

Frontiers in Marine Science, 2015
In contrast to other oligotrophic water bodies the Gulf of Mexico (GOM) hosts an abundance of hydrocarbon seeps, which likely influences the microbial assemblages it hosts particularly regarding the availability of labile carbon in the aphotic GOM.

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, Volume 13, Issue 10, 18 February 2026.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Novel copper-containing membrane monooxygenases (CuMMOs) encoded by alkane-utilizing Betaproteobacteria. [PDF]

, 2020
Copper-containing membrane monooxygenases (CuMMOs) are encoded by xmoCAB(D) gene clusters and catalyze the oxidation of methane, ammonia, or some short-chain alkanes and alkenes.
