Bioremediation via Methanotrophy: Overview of Recent Findings and Suggestions for Future Research [PDF]

Frontiers in Microbiology, 2011
Microbially-mediated bioremediation of polluted sites has been a subject of much research over the past 30 years, with many different compounds shown to be degraded under both aerobic and anaerobic conditions.

Physiological Effect of XoxG(4) on Lanthanide-Dependent Methanotrophy [PDF]

mBio, 2018
A recent surprising discovery of the activity of rare earth metals (lanthanides) as enzyme cofactors as well as transcriptional regulators has overturned the traditional assumption of biological inertia of these metals.

Increased CH₄ Oxidation in Arctic Tundra Ecosystems Caused by Vegetation-Mediated Soil Drying. [PDF]

Glob Chang Biol
In a warmer Arctic, vegetation changes can play a critical role in methane dynamics. Our results indicate that taller vegetation, shifts in species composition, and warmer air temperatures enhance soil aeration by increasing evapotranspiration, thereby promoting methane oxidation in surface soils.

Metals and Methanotrophy [PDF]

Applied and Environmental Microbiology, 2018
ABSTRACT Aerobic methanotrophs have long been known to play a critical role in the global carbon cycle, being capable of converting methane to biomass and carbon dioxide. Interestingly, these microbes exhibit great sensitivity to copper and rare-earth elements, with the expression of key genes involved in the central pathway of methane ...

Examining Archean methanotrophy [PDF]

Earth and Planetary Science Letters, 2016
The carbon isotope ratios preserved in sedimentary rocks can be used to fingerprint ancient metabolisms. Organic carbon in Late Archean samples stands out from that of other intervals with unusually low δ^(13)C values (∼−45 to −60‰). It was hypothesized that these light compositions record ecosystem-wide methane cycling and methanotrophy, either of the

Methanogenesis and methanotrophy within a Sphagnum peatland [PDF]

FEMS Microbiology Ecology, 1995
Abstract Methane production and consumption activities were examined in a Massachusetts peatland. Peat from depths of 5–35 cm incubated under anaerobic conditions, produced an average of 2 nmol CH4 g−1 h−1 with highest rates for peat fractions between 25–30 cm depth. Extracted microbial nucleic acids showed the strongest relative hybridization with a

Methanotrophy across a natural permafrost thaw environment [PDF]

The ISME Journal, 2018
Abstract The fate of carbon sequestered in permafrost is a key concern for future global warming as this large carbon stock is rapidly becoming a net methane source due to widespread thaw. Methane release from permafrost is moderated by methanotrophs, which oxidise 20–60% of this methane before emission to the atmosphere.

Lanthanum anomalies as fingerprints of methanotrophy [PDF]

Geochemical Perspectives Letters, 2020
Methane is an important greenhouse gas whose emissions into the oceans and atmosphere are regulated by relatively unconstrained anaerobic and aerobic microbial processes. The aerobic pathway for methane oxidation is thought to be largely dependent upon the use of rare earth elements (REE), but to date the effects of this process on their abundances in ...

Methanotrophy - Environmental, Industrial and Medical Applications [PDF]

Current Issues in Molecular Biology, 2019
Aerobic methanotrophs are an intriguing group of microbes with the singular ability to consume methane as their sole source of carbon and energy. As such, methanotrophs are receiving increased attention to control methane emissions to limit future climate change. Methanotrophs have a wide range of other applications, including pollutant remediation and

Comparative Analysis of Root Microbiomes of Rice Cultivars with High and Low Methane Emissions Reveals Differences in Abundance of Methanogenic Archaea and Putative Upstream Fermenters. [PDF]

, 2020
Rice cultivation worldwide accounts for ∼7 to 17% of global methane emissions. Methane cycling in rice paddies is a microbial process not only involving methane producers (methanogens) and methane metabolizers (methanotrophs) but also other microbial ...
