Frontiers in Bioengineering and Biotechnology, 2023 Aquatic environments account for half of global CH4 emissions, with freshwater wetlands being the most significant contributors. These CH4 fluxes can be partially offset by aerobic CH4 oxidation driven by methanotrophs.

Ecosystem‐Scale Methane Emissions From Peatlands of the Hudson Bay Lowlands
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.Abstract Northern peatlands are important sources of methane (CH4) in the atmosphere. However, the magnitude of CH4 emissions and their response to environmental factors are poorly constrained within the Hudson Bay Lowlands (HBL), the largest contiguous peatland complex in North America. This study investigated seasonal (April–November) eddy covariance‐

Putative Analogs of Pyrite Suns Forming in Proglacial Alaska Mudflats
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.Abstract Disc‐shaped pyrite suns of the Pennsylvanian age Anna Shale are thought to have formed where pressure restricted pyrite crystal growth to a flattened disc shape during diagenesis at the Anna Shale and the underlying Herrin coal boundary.

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.

Methanotrophic activity and diversity of methanotrophs in volcanic-geothermal soils at Pantelleria island (Italy) [PDF]
, 2014 Volcanic and geothermal systems emit endogenous gases by widespread degassing from soils, including CH4, a greenhouse gas twenty-five times as potent as CO2.

Perspectives for Advancing Biotechnological Succinic Acid Production
Microbial Biotechnology, Volume 19, Issue 5, May 2026.Succinic acid is an important molecule for sustainable chemical manufacturing, but its industrial production faces high costs and sustainability challenges, which are linked to feedstocks and excessive acid/base consumption. This opinion explores production routes based on next‐generation feedstocks and low‐pH fermentations to inspire novel cost ...

From nature to nurture: Essence and methods to isolate robust methanotrophic bacteria
Synthetic and Systems Biotechnology, 2020 Methanotrophic bacteria are entities with innate biocatalytic potential to biofilter and oxidize methane into simpler compounds concomitantly conserving energy, which can contribute to copious industrial applications.

Type II Aerobic Methane Oxidizing Bacteria (AMOB) Drive Methane Oxidation in Pulsed Wetlands as Indicated by 13C-Phospholipid Fatty Acid Composition [PDF]
, 2011 Methane (CH4) is a potent greenhouse gas and management strategies have been proposed to limit CH4 emissions from freshwater wetlands. The methanotrophic bacteria can intercept much of the CH4 produced by methanogenic archaea and thus management ...

Ecohydrology, Volume 19, Issue 3, April/May 2026.ABSTRACT Emissions from trees are an important component of the global methane (CH4) cycle, but their spatial origins (soil vs. in‐stem), transport pathways and environmental influences are not well constrained. To address these issues, this field study characterized spatial and temporal variability in stem emissions of biologically inert radon (222Rn),

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 ...
