Selective, Aerobic Oxidation of Methane to Formaldehyde over Platinum ‐ a Perspective

open access: yesChemCatChem, 2023
AbstractThe direct formation of formaldehyde in the selective, aerobic oxidation of methane in the presence of liquid water at ca. 498 K has recently been described. One of the intriguing observations in the aerobic oxidation of methane over platinum in the presence of water is the absence of the typically observed negative selectivity‐conversion ...

Preliminary Evaluation of In Situ Chemical Oxidation Effects on Soil Carbon Dioxide Emission in a Soil Slurry System

open access: yesRemediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT In situ chemical oxidation (ISCO), a remediation technology for soil and groundwater contamination, utilizes oxidants that can impact the soil environment and indirectly influence soil CO2 emissions. Understanding these emissions may support more sustainable ISCO applications by enabling adjustments to treatment conditions that limit ...

Nitrous oxide act as an alternative electron acceptor for microbial methane oxidation in oxygen-deficient microcosms

open access: yesGeoderma
Submerged paddy is a hotspot of nitrous oxide (N2O) and methane (CH4) emission, which is typically considered electron donor and acceptor for microbes, respectively.

Understanding methanotroph ecology in a biofilter for efficiently mitigating methane emissions : a thesis presented in fulfilment of the requirements for the degree of Doctor of Philosophy in Soil Science (Biotechnology) at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2016
In New Zealand, the majority of the greenhouse gas (GHG), methane (CH4) emissions are from the agriculture sector (enteric fermentation, manure management) and the remainder from solid waste disposal, coal mining and natural gas leaks.

Concentrations of cadmium and arsenic species in rice from production‐scale fields in Arkansas under variable water management

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Rice (Oryza sativa L.) accumulates arsenic when grown under flooded conditions; therefore, alternative water management strategies have shown promise in decreasing grain arsenic. We analyzed polished white rice grain from 103 field‐years of production for arsenic and cadmium.

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 2842-2861, June 2026.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

Genome-Scale Metabolic Model Reconstruction and in Silico Investigations of Methane Metabolism in Methylosinus trichosporium OB3b

open access: yesMicroorganisms, 2020
Methylosinus trichosporium OB3b is an obligate aerobic methane-utilizing alpha-proteobacterium. Since its isolation, M. trichosporium OB3b has been established as a model organism to study methane metabolism in type II methanotrophs. M.

The Particulate Methane Monooxygenase from Methylococcus capsulatus (Bath) Is a Novel Copper-containing Three-subunit Enzyme: isolation and charactization [PDF]

open access: yes, 1998
The particulate methane monooxygenase (pMMO) is known to be very difficult to study mainly due to its unusual activity instability in vitro. By cultivating Methylococcus capsulatus (Bath) under methane stress conditions and high copper levels in the ...
