Difluoromethane, a New and Improved Inhibitor of Methanotrophy [PDF]
Applied and Environmental Microbiology, 1998 ABSTRACT Difluoromethane (HFC-32; DFM) is compared to acetylene and methyl fluoride as an inhibitor of methanotrophy in cultures and soils. DFM was found to be a reversible inhibitor of CH 4 oxidation by Methylococcus capsulatus (Bath). Consumption of CH 4 in

Metals play a pivotal role during one-carbon metabolism as they are important catalysts for numerous enzymatic reactions, can be used for electron transfer, enable radical chemistry, and enhance enzymatic substrate affinity. Metals also coordinate the expression of genes that are involved in their own sensing, sequestration, transport, storage, and use

Methanogenesis and Methanotrophy in Soil: A Review
Pedosphere, 2014Abstract Global warming, as a result of an increase in the mean temperature of the planet, might lead to catastrophic events for humanity. This temperature increase is mainly the result of an increase in the atmospheric greenhouse gases (GHG) concentration.

Simulation of methanotrophy in the mathematical model ecosys
Soil Biology and Biochemistry, 1999Abstract Oxidation by soil-based methanotrophs is an important sink for methane in the soil and atmosphere. Methanotrophy should therefore be explicitly represented in models of CH 4 transfer between soils and the atmosphere. The model for methanotrophy proposed here is based on the kinetics of CH 4 oxidation, as controlled by the biomass and ...

Methanotrophy: An Evolving Field
2018As a field, methanotrophy has emerged in the early twentieth century, marked by the discovery of microbes that could sustain growth on methane gas, using it as the source of both carbon and energy. One hundred plus years later, the field is mature, having accumulated deep knowledge on different modes of methane metabolism, in microbes of different ...

Rates of methanogenesis and methanotrophy in deep‐sea sediments
Geobiology, 2007ABSTRACTWe use the carbon isotopic composition (δ13C) of the dissolved inorganic carbon (DIC) of pore fluids from Leg 175 of the Ocean Drilling Program (ODP) along the West African Margin to quantify rates of methane production (methanogenesis) and destruction via oxidation (methanotrophy) in deep‐sea sediments.

Seasonal methanotrophy across a hydrological gradient in a freshwater wetland
Ecological Engineering, 2014Abstract Wetlands provide significant ecosystem services but are also the largest natural source of methane (CH 4 ), a critical greenhouse gas. Oxidation of CH 4 in soils/sediments, driven by methanotrophs, offsets CH 4 losses to the atmosphere. Manipulation of flooding regimes to optimize methanotrophy is a potential management strategy to reduce ...

Methanotrophy: From the environment to industry and back
Chemical Engineering Journal, 2010Understanding concerning natural microbially mediated processes has been severely retarded by the common requirement to study microorganisms only as pure monocultures under aseptic conditions, in spite of the fact that, in virtually all real environments, microbial strains function in concert.

Methanotrophy at hydrothermal vents: A missing methane sink
2023Microbial methane oxidation plays a critical role curbing methane emissions from the seafloor into the atmosphere and is widely considered to be the largest marine methane “sink”. Hydrothermal vent systems are ubiquitous, geologically diverse, and produce >70% of the abiotic mid-ocean methane flux to the hydrosphere. However, their methane oxidizing

Methanotrophy Goes Commercial: Challenges, Opportunities, and Brief History
2018Methane is an advantaged feedstock due to its high energy density and widespread abundance. Prices of methane are at historic lows due to modern natural gas extraction techniques and advances in biogas generation by anaerobic digestion. The availability of genetically tractable methanotrophs that can grow readily in industrial settings and new ...
