Monodeuterated Methane, an Isotopic Tool To Assess Biological Methane Metabolism Rates

mSphere, 2017
Biological methane oxidation is a globally relevant process that mediates the flux of an important greenhouse gas through both aerobic and anaerobic metabolic pathways.

Methane-related changes in prokaryotes along geochemical profiles in sediments of Lake Kinneret (Israel) [PDF]

Biogeosciences, 2015
Microbial methane oxidation is the primary control on the emission of the greenhouse gas methane into the atmosphere. In terrestrial environments, aerobic methanotrophic bacteria are largely responsible for this process.

Sustainable Power Production in a Membrane-less and Mediator-less Wastewater Microbial Fuel Cell [PDF]

, 2009
Microbial fuel cells (MFCs) fed with wastewater are currently considered a feasible strategy for production of renewable electricity at low cost. A membrane-less MFC with biological cathode was built from a compact wastewater treatment reactor.

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

mLife, EarlyView.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...

Photocatalytic aerobic oxidative carbonylation of methane by iron terpyridine catalysts [PDF]

, 2020
Abstract Employing methane as a C1 feedstock for commodity chemicals represents a sustainable and empowering opportunity for chemical catalysis. However, practical demands of industrial development have imposed serve challenges to utilize co-effective catalysts and reagents as well as ecologically benign conditions for highly efficient and ...

Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

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 ...

Timescale dependence of environmental and plant‐mediated controls on CH4 flux in a temperate fen [PDF]

, 2007
This study examined daily, seasonal, and interannual variations in CH4 emissions at a temperate peatland over a 5‐year period. We measured net ecosystem CO2 exchange (NEE), CH4 flux, water table depth, peat temperature, and meteorological parameters ...

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...
