Life in the extreme: thermoacidophilic methanotrophy
Trends in Microbiology, 2008Aerobic methane-oxidizing bacteria (methanotrophs) have a key role in the global carbon cycle, converting methane to biomass and carbon dioxide. Although these bacteria have been isolated from many environments, until recently, it was not known if they survived, much less thrived in thermoacidic environments, that is, locations with pH values of ...

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

Engineered Methanotrophy: A Sustainable Solution for Methane-Based Industrial Biomanufacturing
Trends in Biotechnology, 2021Methane is a promising feedstock with high abundance and low cost for the sustainable production of biochemicals and biofuels. Methanotrophic bacteria are particularly interesting platforms for methane bioconversion as they can utilize methane as a carbon substrate.

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.

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
