Methane-Dependent Mineral Reduction by Aerobic Methanotrophs under Hypoxia

Environmental Science & Technology Letters, 2020
Methanotrophs play an important role in controlling methane balance in the biosphere. For over 100 years, methanotrophs of the Proteobacteria phylum have been studied under oxic conditions, with mo...

Physiology and Biochemistry of the Aerobic Methanotrophs

2018
Methanotrophs are a widely distributed group of aerobic bacteria that use methane as their source of carbon and energy. They play key roles in the global carbon cycle, including controlling anthropogenic and natural emissions of the greenhouse gas methane.

Properties of Malic Enzyme from the Aerobic Methanotroph Methylosinus trichosporium

Biochemistry (Moscow), 2019
Recombinant malic enzyme from the aerobic methanotroph Methylosinus trichosporium was obtained by heterologous expression in Escherichia coli and purified by affinity metal-chelating chromatography. The homohexameric enzyme of 6×80 kDa catalyzed the reversible reaction of oxidative decarboxylation of malate to pyruvate in the presence of mono- and ...

Diversity and Phylogeny of Described Aerobic Methanotrophs

2018
Aerobic methanotrophs are metabolically unique bacteria that are able to utilize methane as a sole source of energy. They occur in a wide range of habitats where both methane and oxygen are available. Nearly all methanotrophic bacteria that are now isolated in pure cultures belong to the phylum Proteobacteria, while only a limited number of strains ...

Aerobic and anaerobic methanotrophs in the Black Sea water column

Environmental Microbiology, 2006
Summary Inputs of CH 4 from sediments, including methane seeps on the continental margin and methane‐rich mud volcanoes on the abyssal plain, make the Black Sea the world’s largest surface water reservoir of dissolved methane and drive a high rate of aerobic and anaerobic ...

Enrichment and Isolation of Aerobic and Anaerobic Methanotrophs

2019
Methanotrophs mediate methane oxidation to produce CO2 which is facilitated by methane monooxygenase. Owing to this unique nature, methanotrophs are required in many industrial processes and have environmental applications. For this purpose, diverse aerobic proteobacterial and verrucomicrobial methanotrophs with different traits have been isolated and ...

Activity and species composition of aerobic methanotrophic communities in tundra soils

Current Microbiology, 1993
The low-temperature, methane-oxidizing activities and species composition of methanotrophic communities in various tundra bog soils were investigated by radioisotopic and immunofluorescent methods. Methanotrophic bacteria carried out the methane oxidation process through all horizons of seasonally thawed layers down to permafrost.

Aerobic methanotrophs from the coastal thermal springs of Lake Baikal

Microbiology, 2009
The number, activity, and diversity of aerobic methanotrophic bacteria in the sediments of three coastal thermal springs of Lake Baikal were analyzed. The average number of methanotrophs was 103–104 cells per 1 cm3 of sediment. The highest number of methanotrophs (108 cells/cm3 of silt) and the highest potential rate of methane uptake [7.7 nmol CH4 ...

Laboratory-based aerobic denitrification using methanotrophic biomass as substrate.

2020
Nitrate levels in our water resources have doubled since 20th century. This is largely due to anthropogenic activities such as overuse of nitrogen fertilizers, combustion of fossil fuels, and improper disposal of human and animal waste. Drinking water with high nitrate concentration can be highly toxic and is known to be associated with ...
