Impact of Copper on the Physiology and Transcriptome of Methylosinus Trichosporium OB3b Grown on Either Methane or Methanol. [PDF]

Environ Microbiol
Methylosinus trichosporium OB3b can grow on methanol in the absence but not presence of copper due: (1) overgeneration of reducing power from methanol oxidation; (2) formate accumulation leading to acidification of the growth medium and inactivation of formate dehydrogenase; and (3) lack of expression of potential oxidative stress defence genes ...

Investigation on the aerobic methanotrophic community and the dominant taxon Methylomarinum in seagrass ecosystem [PDF]

Environmental Microbiome
Background Methanotrophs are a key biological methane sink, and aerobic methanotrophs critically reduce wetland methane emissions under global climate change.

Optimum O2:CH4 Ratio Promotes the Synergy between Aerobic Methanotrophs and Denitrifiers to Enhance Nitrogen Removal [PDF]

Frontiers in Microbiology, 2017
The O2:CH4 ratio significantly effects nitrogen removal in mixed cultures where aerobic methane oxidation is coupled with denitrification (AME-D). The goal of this study was to investigate nitrogen removal of the AME-D process at four different O2:CH4 ...

Methanotrophs: Discoveries, Environmental Relevance, and a Perspective on Current and Future Applications

Frontiers in Microbiology, 2021
Methane is the final product of the anaerobic decomposition of organic matter. The conversion of organic matter to methane (methanogenesis) as a mechanism for energy conservation is exclusively attributed to the archaeal domain.

No evidence of light inhibition on aerobic methanotrophs in coastal sediments using eDNA and eRNA

Environmental DNA, 2023
It is estimated that up to half of global methane (CH4) emissions are derived from microbial processes in aquatic ecosystems. However, it is not fully understood which factors explain the spatial and temporal variability of these emissions.

Diversity and Effect of Increasing Temperature on the Activity of Methanotrophs in Sediments of Fildes Peninsula Freshwater Lakes, King George Island, Antarctica

Frontiers in Microbiology, 2022
Global warming has a strong impact on polar regions. Particularly, the Antarctic Peninsula and nearby islands have experienced a marked warming trend in the past 50 years.

Identification of functionally active aerobic methanotrophs and their methane oxidation potential in sediments from the Shenhu Area, South China Sea

China Geology, 2022
: Large amounts of gas hydrate are distributed in the northern slope of the South China Sea, which is a potential threat of methane leakage. Aerobic methane oxidation by methanotrophs, significant methane biotransformation that occurs in sediment surface

Aerobic methanotrophy increases the net iron reduction in methanogenic lake sediments

Frontiers in Microbiology, 2023
In methane (CH4) generating sediments, methane oxidation coupled with iron reduction was suggested to be catalyzed by archaea and bacterial methanotrophs of the order Methylococcales. However, the co-existence of these aerobic and anaerobic microbes, the

Novel Methanotrophs of the Family Methylococcaceae from Different Geographical Regions and Habitats [PDF]

, 2015
Terrestrial methane seeps and rice paddy fields are important ecosystems in the methane cycle. Methanotrophic bacteria in these ecosystems play a key role in reducing methane emission into the atmosphere.

Batch Experiments Demonstrating a Two-Stage Bacterial Process Coupling Methanotrophic and Heterotrophic Bacteria for 1-Alkene Production From Methane

Frontiers in Microbiology, 2022
Methane (CH4) is a sustainable carbon feedstock for value-added chemical production in aerobic CH4-oxidizing bacteria (methanotrophs). Under substrate-limited (e.g., oxygen and nitrogen) conditions, CH4 oxidation results in the production of various ...
