Frontiers in Microbiology, 2021 Methane is the final product of the anaerobic decomposition of organic matter. The conversion of organic matter to methane (methanogenesis) as a mechanism for energy conservation is exclusively attributed to the archaeal domain.

Riverbed methanotrophy sustained by high carbon conversion efficiency [PDF]
The ISME Journal, 2015 Abstract Our understanding of the role of freshwaters in the global carbon cycle is being revised, but there is still a lack of data, especially for the cycling of methane, in rivers and streams. Unravelling the role of methanotrophy is key to determining the fate of methane in rivers.

The origin, source and cycling of methane in deep crystalline rock biosphere
Frontiers in Microbiology, 2015 The emerging interest in using stable bedrock formations for industrial purposes, e.g. nuclear waste disposal, has increased the need for understanding microbiological and geochemical processes in deep crystalline rock environments, including the carbon ...

Frontiers in Microbiology, 2022 Verrucomicrobia are a group of microorganisms that have been proposed to be deeply rooted in the Tree of Life. Some are methanotrophs that oxidize the potent greenhouse gas methane and are thus important in decreasing atmospheric concentrations of the ...

River Research and Applications, EarlyView.ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...

Extraordinary methane levels in a small bar‐built tropical estuary
Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.Abstract Small estuaries link uplands and nearshore marine environments but are understudied in many regions. We quantified spatial and temporal variability in CH4, CO2, nutrients, and organic matter in a small, deep, bar‐built tropical estuary in Fajardo, Puerto Rico.
