Electron and Proton Flux for Carbon Dioxide Reduction in Methanosarcina barkeri During Direct Interspecies Electron Transfer

Frontiers in Microbiology, 2018
Direct interspecies electron transfer (DIET) is important in diverse methanogenic environments, but how methanogens participate in DIET is poorly understood.

The Evolution of Microbial Facilitation: Sociogenesis, Symbiogenesis, and Transition in Individuality

Frontiers in Ecology and Evolution, 2022
Metabolic cooperation is widespread, and it seems to be a ubiquitous and easily evolvable interaction in the microbial domain. Mutual metabolic cooperation, like syntrophy, is thought to have a crucial role in stabilizing interactions and communities ...

Novel microbial syntrophies identified by longitudinal metagenomics [PDF]

, 2021
ABSTRACT Identifying species interactions in a microbial community and how this relates to community function is a key challenge. Towards addressing this challenge, we present here an extensive genome-resolved, longitudinal dataset and associated metadata.

B-Vitamin Sharing Promotes Stability of Gut Microbial Communities

Frontiers in Microbiology, 2019
Cross-feeding on intermediary and end-point metabolites plays an important role in the dynamic interactions of host-associated microbial communities. While gut microbiota possess inherent resilience to perturbation, variations in the intake of certain ...

The Syntrophy Hypothesis for the Origin of Eukaryotes [PDF]

, 2006
The syntrophy hypothesis proposes an evolutionary pathway for the origin of eukaryotes based primarily on a symbiotic event between methanogenic archaea and facultative fermentative-sulfate reducing δ-protcobacteria (ancestral myxobacteria). The mitochondrial symbiosis is an independent event involving methane-oxidizing α-proteobacteria.

Methane-Fueled Syntrophy through Extracellular Electron Transfer: Uncovering the Genomic Traits Conserved within Diverse Bacterial Partners of Anaerobic Methanotrophic Archaea

mBio, 2017
The anaerobic oxidation of methane by anaerobic methanotrophic (ANME) archaea in syntrophic partnership with deltaproteobacterial sulfate-reducing bacteria (SRB) is the primary mechanism for methane removal in ocean sediments.

Seasonal Restructuring of Microbial Communities and Resistomes in the Shitalakshya River, Bangladesh Revealed by Shotgun Metagenomics

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Dry‐season pollutant concentration drives microbial restructuring in Bangladesh's Shitalakshya River, shifting communities from Myroides to stress‐tolerant genera while enriching metal resistance genes and efflux pumps, revealing non‐antibiotic co‐selection as a key driver of antimicrobial resistance in urban waters.

Effects of Temperature on Mercury Methylation and Demethylation in Boreal Wetland Soils

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Wetlands are critical sites for methylmercury (MeHg) production, a neurotoxin that bioaccumulates in organisms and biomagnifies in aquatic food webs. Net MeHg production in wetland soil depends on the balance between microbially mediated MeHg production and the degradation of MeHg through both microbial and abiotic pathways.
