De-oxygenation of CO2 by using Hydrogen, Carbon and Methane over Alumina-Supported Catalysts [PDF]

, 2012
The de-oxygenation of CO2 was explored by using hydrogen, methane, carbon etc., over alumina supported catalysts. The alumina-supported ruthenium, rhodium, platinum, molybdenum, vanadium and magnesium catalysts were first reduced in hydrogen atmosphere ...

A phenotype‐based framework to measure functional redundancy in microbial ecosystems

Methods in Ecology and Evolution, EarlyView.
Abstract Functional redundancy is a key biological concept that offers critical insights into microbial ecosystem stability and responses to environmental perturbations. Existing methods to quantify redundancy typically rely on gene annotations as functional units, limiting their ability to capture complex or partially characterised traits and making ...

a low-activity cold seep in the Larsen B area, western Weddell Sea, Antarctica [PDF]

, 2008
First videographic indication of an Antarctic cold seep ecosystem was recently obtained from the collapsed Larsen B ice shelf, western Weddell Sea (Domack et al., 2005).

Delivering Sulfate to LNAPL Body for Enhanced Source Zone Depletion (ESZD)

Groundwater Monitoring &Remediation, EarlyView.
Abstract This field pilot study evaluates the feasibility of applying sulfate to a light non‐aqueous phase liquid (LNAPL) body for achieving enhanced source zone depletion (ESZD) at a refinery site. Two rounds of gypsum land application (GLA) delivered sulfate to an 8000 ft2 area encompassing LNAPL‐containing monitoring wells MW‐2 and MW‐3, while MW‐1 ...

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

Microorganisms, 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.

Belowground growth is the primary driver of radial oxygen loss from Typha angustifolia to sediment

New Phytologist, EarlyView.
Oxygen pool accompanying the growth of a new Typha angustifolia rhizome through anoxic sediment. Summary Wetland plants must supply oxygen to their rhizomes and roots to maintain aerobic respiration despite soil anoxia. Excess oxygen can diffuse into the environment, strongly affecting rhizosphere biogeochemistry.

Methane to Liquid Fuels over Metal Loaded HZSM-5 Catalyst [PDF]

, 2011
ZSM-5 zeolite is an acidic catalyst that is highly potential for the conversion of natural gas to liquid fuels. One of the variables that controls the acidity of the ZSM-5 is its Si/Al ratio.

Climate benefits of wetland restoration are constrained by slow vegetation recovery

Restoration Ecology, EarlyView.
Abstract Introduction Wetland restoration is widely used to enhance ecosystem resilience, biodiversity, and climate mitigation. However, restoring hydrology may not lead to rapid vegetation establishment or reduced greenhouse gas (GHG) emissions in severely degraded wetlands.

Coupling methane oxidation to pollutant transformation: a microbiome framework for climate mitigation and soil remediation

Soil & Environmental Health
Methane emissions and chemical pollutants often co-occur in natural and engineered environments, contributing to ecosystem degradation. Microorganisms play key roles in regulating these processes through methane oxidation and pollutant transformation ...
