Global peatland greenhouse gas dynamics: state of the art, processes, and perspectives

open access: yesNew Phytologist, Volume 246, Issue 1, Page 94-102, April 2025.
Summary Natural peatlands regulate greenhouse gas (GHG) fluxes through a permanently high groundwater table, causing carbon dioxide (CO2) assimilation but methane (CH4) emissions due to anaerobic conditions. By contrast, drained and disturbed peatlands are hotspots for CO2 and nitrous oxide (N2O) emissions, while CH4 release is low but high from ...

Isolation and Characterization of Methanotrophic Bacteria From Rice Fields [PDF]

open access: yes, 2009
Methane is a greenhouse gas and has potency to deplete ozone layer. Rice fields are a significantly sources of atmospheric methane. Chemical fertilizers application in rice fields can increase methane emission.

Methylovulum miyakonense gen. nov., sp. nov., a type I methanotroph isolated from forest soil. [PDF]

open access: yes, 2011
A novel methanotroph, designated strain HT12(T), was isolated from forest soil in Japan. Cells of strain HT12(T) were Gram-reaction-negative, aerobic, non-motile, coccoid and formed pale-brown colonies.

Abrupt Changes in the Timing and Magnitude of the North Atlantic Bloom Over the 21st Century

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 3, March 2025.
Abstract The North Atlantic subpolar gyre (SPG) is a key region for the North Atlantic bloom (NAB), the phytoplankton foundation of the regional food web. The NAB depends on nutrients seasonally introduced into the surface ocean by deep winter convection.

Nitric Oxide Dismutase (nod) Genes as a Functional Marker for the Diversity and Phylogeny of Methane-Driven Oxygenic Denitrifiers

open access: yesFrontiers in Microbiology, 2019
Oxygenic denitrification represents a new route in reductive nitrogen turnover which differs from canonical denitrification in how nitric oxide (NO) is transformed into dinitrogen gas.

Sphagnum-associated methanotrophs : a resilient CH4 biofilter in pristine and disturbed peatlands [PDF]

open access: yes, 2018
Boreal peatlands are highly important sinks for carbon (C). This function is enabled largely by one peat-forming plant, the Sphagnum moss. In addition to slowing the decomposition by gradually creating ombrotrophic conditions, it gives a shelter for the ...

Suppression of Methanogenesis by Microbial Reduction of Iron‐Organic Carbon Associations in Fully Thawed Permafrost Soil

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 3, March 2025.
Abstract Global methane (CH4) emissions from thawing permafrost peatlands are expected to increase substantially in the future. Net emission of CH4 depends on the presence of more favorable terminal electron acceptors for microbial respiration, such as ferric iron (Fe(III)).

Response of methanotrophic activity and community structure to temperature changes in a diffusive CH4/O2 counter gradient in an unsaturated porous medium [PDF]

open access: yes, 2017
Microbial methane oxidation is a key process in the global methane cycle. In the context of global warming, it is important to understand the responses of the methane-oxidizing microbial community to temperature changes in terms of community structure ...

Comparative in silico analysis of PCR primers suited for diagnostics and cloning of ammonia monooxygenase genes from ammonia-oxidizing bacteria [PDF]

open access: yes, 2008
Over recent years, several PCR primers have been described to amplify genes encoding the structural subunits of ammonia monooxygenase (AMO) from ammonia-oxidizing bacteria (AOB).

Biochar-based urea increases soil methane uptake in a subtropical forest

open access: yesGeoderma
Novel biochar-based fertilizers, produced by combining biochar particles with chemical fertilizers, have strong potential to enrich soil with carbon (C) and nitrogen (N), and to increase plant productivity.
