Characteristics of Microbial Community Structure at the Seafloor Surface of the Nankai Trough

Journal of Pure and Applied Microbiology, 2019
Phylogenetic analysis of bacteria and archaea on the seafloor surface of the Nankai Trough was conducted. DNA was extracted from a total of 14 samples (2 samples from 1 methane seep area and 12 samples from 12 general seafloor areas) and analyzed ...

Methane-Dependent Extracellular Electron Transfer at the Bioanode by the Anaerobic Archaeal Methanotroph “Candidatus Methanoperedens”

Frontiers in Microbiology, 2022
Anaerobic methanotrophic (ANME) archaea have recently been reported to be capable of using insoluble extracellular electron acceptors via extracellular electron transfer (EET).

On the behaviour of the ANM continuation in the presence of bifurcations [PDF]

Communications in Numerical Methods in Engineering, 2003
AbstractThe asymptotic‐numerical method (ANM) is a path following technique which is based on high order power series expansions. In this paper, we analyse its behaviour when it is applied to the continuation of a branch with bifurcation points. We show that when the starting point of the continuation is near a bifurcation, the radius of convergence of

Comparative Genomics and Proteomic Analysis of Assimilatory Sulfate Reduction Pathways in Anaerobic Methanotrophic Archaea

Frontiers in Microbiology, 2018
Sulfate is the predominant electron acceptor for anaerobic oxidation of methane (AOM) in marine sediments. This process is carried out by a syntrophic consortium of anaerobic methanotrophic archaea (ANME) and sulfate reducing bacteria (SRB) through an ...

A PCR-Based Survey of Methane-Cycling Archaea in Methane-Soaked Subsurface Sediments of Guaymas Basin, Gulf of California

Microorganisms, 2023
The Guaymas Basin in the Gulf of California is characterized by active seafloor spreading, the rapid deposition of organic-rich sediments, steep geothermal gradients, and abundant methane of mixed thermogenic and microbial origin.

Unexpected scarcity of ANME archaea in hydrocarbon seeps within Monterey Bay [PDF]

Biogeosciences
Marine hydrocarbon seeps typically harbor a relatively predictable microbiome, including anaerobic methanotrophic (ANME) archaea. Here, we sampled two cold seeps in Monterey Bay, CA – Clam Field and Extrovert Cliff – which have been known for decades but

Isotopologue Ratios Identify ¹³C-Depleted Biomarkers in Environmental Samples Impacted by Methane Turnover. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale The stable carbon isotopic composition (δ13C) of individual lipids is of great value in studying carbon cycling. Among those, microbial lipids in sediments impacted by high methane turnover stand out due to their uniquely depleted isotopic fingerprint.

Contrasting Pathways for Anaerobic Methane Oxidation in Gulf of Mexico Cold Seep Sediments

mSystems, 2019
Gulf of Mexico sediments harbor numerous hydrocarbon seeps associated with high sedimentation rates and thermal maturation of organic matter. These ecosystems host abundant and diverse microbial communities that directly or indirectly metabolize ...

Anthropogenic and Environmental Constraints on the Microbial Methane Cycle in Coastal Sediments

Frontiers in Microbiology, 2021
Large amounts of methane, a potent greenhouse gas, are produced in anoxic sediments by methanogenic archaea. Nonetheless, over 90% of the produced methane is oxidized via sulfate-dependent anaerobic oxidation of methane (S-AOM) in the sulfate-methane ...
