Isoprene oxidation by the gram-negative model bacterium variovorax sp. WS11 [PDF]

, 2020
Plant-produced isoprene (2-methyl-1,3-butadiene) represents a significant portion of global volatile organic compound production, equaled only by methane.

Simultaneous Anaerobic and Aerobic Ammonia and Methane Oxidation under Oxygen Limitation Conditions

Applied and Environmental Microbiology, 2021
Nitrogen in wastewater leads to eutrophication of the receiving water bodies, and methane is a potent greenhouse gas; it is therefore important that these are removed from wastewater. A potential solution for the simultaneous removal of nitrogenous compounds and methane is the application of a combination of nitrite/nitrate-dependent methane oxidation (

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 ...

Active Methanotrophs in Suboxic Alpine Swamp Soils of the Qinghai–Tibetan Plateau

Frontiers in Microbiology, 2020
Methanotrophs are the only biofilters for reducing the flux of global methane (CH4) emissions in water-logged wetlands. However, adaptation of aerobic methanotrophs to low concentrations of oxygen and nitrogen in typical swamps, such as that of the ...

Landfill aeration for emission control before and during landfill mining [PDF]

, 2015
The landfill of Modena, in northern Italy, is now crossed by the new high velocity railway line connecting Milan and Bologna. Waste was completely removed from a part of the landfill and a trench for the train line was built. With the aim of facilitating

Geographic and seasonal variation of dissolved methane and aerobic methane oxidation in Alaskan lakes [PDF]

Biogeosciences, 2015
Abstract. Methanotrophic bacteria play an important role oxidizing a significant fraction of methane (CH4) produced in lakes. Aerobic CH4 oxidation depends mainly on lake CH4 and oxygen (O2) concentrations, in such a manner that higher MO rates are usually found at the oxic/anoxic interface, where both molecules are present.

Microbial Communities Involved in Methane, Sulfur, and Nitrogen Cycling in the Sediments of the Barents Sea

Microorganisms, 2021
A combination of physicochemical and radiotracer analysis, high-throughput sequencing of the 16S rRNA, and particulate methane monooxygenase subunit A (pmoA) genes was used to link a microbial community profile with methane, sulfur, and nitrogen cycling ...

Ensiling and Fermentation of Rice Hulls With Ruminal Fluid for Medium‐Chain Carboxylate Production

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Large quantities of rice hulls are common at milling sites in Nigeria. They are a by‐product of rice processing and can contribute to environmental degradation if not properly managed. In this study, rice hulls were pretreated by ensiling at ambient temperature and then used as substrate for medium‐chain carboxylates (MCCs) production ...

Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.

Biodegradation of plastic wastes under semi-aerobic condition with active methane oxidation activities and nutrient supply

Case Studies in Chemical and Environmental Engineering
Elimination of plastic waste deposition in landfills is essential to avoid secondary pollution such as microplastics. Under appropriate environments, methanotrophs which proceed through methane oxidation reaction are capable of degrading plastics via ...
