Variations in Concentration and Carbon Isotope Composition of Methanotroph Biomarkers in Sedge Peatlands Along the Altitude Gradient in the Changbai Mountain, China

Frontiers in Microbiology, 2022
Northern peatlands are one of the largest natural sources of atmospheric methane globally. As the only biological sink of methane, different groups of methanotrophs use different carbon sources. However, the variations in microbial biomass and metabolism

Differential Transcriptional Activation of Genes Encoding Soluble Methane Monooxygenase in a Facultative Versus an Obligate Methanotroph

Microorganisms, 2018
Methanotrophs are a specialized group of bacteria that can utilize methane (CH4) as a sole energy source. A key enzyme responsible for methane oxidation is methane monooxygenase (MMO), of either a soluble, cytoplasmic type (sMMO), or a particulate ...

DSOF: A Rapid Method to Determine the Abundance of Microalgae and Methanotrophic Bacteria in Coculture Using a Combination of Differential Sedimentation, Optical Density, and Fluorescence [PDF]

Bioengineering
Cocultivation of microalgae and aerobic methanotrophs represents an emerging biotechnology platform to produce high-protein biomass, yet quantifying individual species in mixed cultures remains challenging.

First isolation of a methanotrophic Mycobacterium reveals ammonia- and pH-tolerant methane oxidation [PDF]

Applied and Environmental Microbiology
Methanotrophs facilitate a key step in the global carbon cycle—oxidation of natural and anthropogenic methane—and comprehension of their physiology is critical in unraveling the ecology revolving around microbial methane sinks.

Activity and abundance of methane-oxidizing bacteria in secondary forest and manioc plantations of Amazonian Dark Earth and their adjacent soils

Frontiers in Microbiology, 2014
The oxidation of atmospheric CH4 in upland soils is mostly mediated by uncultivated groups of microorganisms that have been identified solely by molecular markers, such as the sequence of the pmoA gene encoding the β-subunit of the particulate methane ...

Effects of a Single Cell Protein (Methylococcus capsulatus, Bath) in Pacific White Shrimp (Penaeus vannamei) Diet on Growth Performance, Survival Rate and Resistance to Vibrio parahaemolyticus, the Causative Agent of Acute Hepatopancreatic Necrosis Disease

Frontiers in Marine Science, 2021
The efficacy of a single cell protein (SCP) methanotroph (Methylococcus capsulatus, Bath) bacteria meal (FeedKind®, Calysta, Menlo Park, CA, United States), in Pacific white shrimp (Penaeus vannamei) diets was studied to determine growth performance ...

The Influence of Above-Ground Herbivory on the Response of Arctic Soil Methanotrophs to Increasing CH₄ Concentrations and Temperatures

Microorganisms, 2021
Rising temperatures in the Arctic affect soil microorganisms, herbivores, and peatland vegetation, thus directly and indirectly influencing microbial CH4 production.

Nitrogen addition decreases methane uptake caused by methanotroph and methanogen imbalances in a Moso bamboo forest

Scientific Reports, 2021
Forest soils play an important role in controlling global warming by reducing atmospheric methane (CH4) concentrations. However, little attention has been paid to how nitrogen (N) deposition may alter microorganism communities that are related to the CH4

Lake mixing regime selects apparent methane oxidation kinetics of the methanotroph assemblage [PDF]

Biogeosciences, 2020
In lakes, large amounts of methane are produced in anoxic sediments. Methane-oxidizing bacteria effectively convert this potent greenhouse gas into biomass and carbon dioxide.
