Light rare earth element depletion during Deepwater Horizon blowout methanotrophy [PDF]

Scientific Reports, 2017
Rare earth elements have generally not been thought to have a biological role. However, recent work has demonstrated that the light REEs (LREEs: La, Ce, Pr, and Nd) are essential for at least some methanotrophs, being co-factors in the XoxF type of ...

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 ...

Microbial Community Dynamics in Early Tufa Biofilms. [PDF]

Microbiologyopen
Microbial succession shapes the early development of tufa biofilms in karst freshwater systems, with prokaryotic communities stabilizing rapidly and microeukaryotes contributing to extracellular polymeric substance production and carbonate entrapment. Site‐specific hydrodynamics and organic inputs drive community specialization, ultimately influencing ...

Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub-Arctic Waterbodies in Northern Canada. [PDF]

Environ Microbiol
Prokaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

Responses of Low-Cost Input Combinations on the Microbial Structure of the Maize Rhizosphere for Greenhouse Gas Mitigation and Plant Biomass Production

Frontiers in Plant Science, 2021
The microbial composition of the rhizosphere and greenhouse gas (GHG) emissions under the most common input combinations in maize (Zea mays L.) cultivated in Brazil have not been characterized yet.

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

Polyhydroxybutyrate Production from Methane and Carbon Dioxide by a Syntrophic Consortium of Methanotrophs with Oxygenic Photogranules without an External Oxygen Supply

Microorganisms, 2023
Here, a syntrophic process was developed to produce polyhydroxy-β-butyrate (PHB) from a gas stream containing CH4 and CO2 without an external oxygen supply using a combination of methanotrophs with the community of oxygenic photogranules (OPGs).

Soil methane sink capacity response to a long-term wildfire chronosequence in Northern Sweden [PDF]

, 2015
Boreal forests occupy nearly one fifth of the terrestrial land surface and are recognised as globally important regulators of carbon (C) cycling and greenhouse gas emissions.

In Vivo Evidence of Single 13C and 15N Isotope–Labeled Methanotrophic Nitrogen-Fixing Bacterial Cells in Rice Roots

mBio, 2022
Methane-oxidizing bacteria (methanotrophs) play an ecological role in methane and nitrogen fluxes because they are capable of nitrogen fixation and methane oxidation, as indicated by genomic and cultivation-dependent studies.

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
