Geobacter-based syntrophy drives biogenic element cycling in anoxic soils: a review [PDF]

Frontiers in Microbiology
Microbial syntrophy is a central organizing principle in anoxic soils, where the degradation of organic matter and the cycling of nitrogen, sulfur, and iron are constrained by electron availability and thermodynamics.

Host-initiated microbial association leads to stable ectosymbiosis in an ecological model. [PDF]

PLoS Computational Biology
Microbial symbiosis is widespread among metabolically coupled cells; it presumably gave rise to mitochondria. However, how such symbioses emerge, evolve, and stabilize are unknown, particularly in the prokaryotic domain where endosymbiosis is virtually ...

Enhancement of methanogenesis by electric syntrophy with biogenic iron-sulfide minerals

MicrobiologyOpen, 2019
Recent studies have shown that interspecies electron transfer between chemoheterotrophic bacteria and methanogenic archaea can be mediated by electric currents flowing through conductive iron oxides, a process termed electric syntrophy. In this study, we

Syntrophy emerges spontaneously in complex metabolic systems

PLoS Computational Biology, 2019
Syntrophy allows a microbial community as a whole to survive in an environment, even though individual microbes cannot. The metabolic interdependence typical of syntrophy is thought to arise from the accumulation of degenerative mutations during the ...

Mathematical model of anaerobic digestion in a chemostat: effects of syntrophy and inhibition

Journal of Biological Dynamics, 2013
Three of the four main stages of anaerobic digestion: acidogenesis, acetogenesis, and methanogenesis are described by a system of differential equations modelling the interaction of microbial populations in a chemostat.

Comparative proteogenomics reveals ecological and evolutionary insights into the organohalide-respiring Dehalobacter restrictus strain T [PDF]

Applied and Environmental Microbiology
1,1,1-Trichloroethane (1,1,1-TCA) and chloroform (CF) are persistent groundwater contaminants because of their widespread industrial use as organic solvents and improper disposal in the past.

Reactive Oxygen and Sulfur Species: Partners in Crime

Oxygen, 2022
The emergence of complexity requires cooperation, yet selection typically favors defectors that do not cooperate. Such evolutionary conflict can be alleviated by a variety of mechanisms, allowing complexity to emerge.

“Candidatus Ethanoperedens,” a Thermophilic Genus of Archaea Mediating the Anaerobic Oxidation of Ethane

mBio, 2020
Cold seeps and hydrothermal vents deliver large amounts of methane and other gaseous alkanes into marine surface sediments. Consortia of archaea and partner bacteria thrive on the oxidation of these alkanes and its coupling to sulfate reduction.

Microbial interspecies interactions: recent findings in syntrophic consortia

Frontiers in Microbiology, 2015
Microbes are ubiquitous in our biosphere, and inevitably live in communities. They excrete a variety of metabolites and support the growth of other microbes in a community.

Simultaneous Genome Sequencing of Prosthecochloris ethylica and Desulfuromonas acetoxidans within a Syntrophic Mixture Reveals Unique Pili and Protein Interactions

Microorganisms, 2020
Strains of Chloropseudomonas ethylica, 2-K, N2, and N3 are known to be composed of a syntrophic mixture of a green sulfur bacterium and a sulfur-reducing colorless component.
