Metabolic Aspects of Aerobic Obligate Methanotrophy⋆
2008Publisher Summary This chapter discusses the metabolic aspects of aerobic obligate methanotrophy. Aerobic methanotrophs are a unique group of gram-negative bacteria that use methane as carbon and energy source. Methanotrophs have been studied intensively over the past 40 years since these bacteria possess significant metabolic potential for practical

Anaerobic methanotrophy and the rise of atmospheric oxygen
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007In modern marine sediments, the anoxic decomposition of organic matter generates a significant flux of methane that is oxidized microbially with sulphate under the seafloor and never reaches the atmosphere. In contrast, prior to ca 2.4 Gyr ago, the ocean had little sulphate to support anaerobic oxidation of methane (

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.

Microbial methane oxidation has a significant impact on the methane flux from marine gas hydrate areas. However, the environmental fate of methane remains poorly constrained. We quantified the relative contributions of aerobic and anaerobic methanotrophs

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 ...

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 ...

Proteomic evidence of methanotrophy in methane‐enriched hypolimnetic lake water
Limnology and Oceanography, 2016AbstractFreshwaters have recently been recognized as important sources of methane emitted to the atmosphere, and microbial methane oxidation at the oxic/anoxic interface is a key process controlling these emissions. We applied proteomics to determine enzyme expression patterns of methanotrophs in response to methane enrichment of lake water. In a small‐

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 ...
