Syntrophy emerges spontaneously in complex metabolic systems.
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 ...

Enhancement of methanogenesis by electric syntrophy with biogenic iron‐sulfide minerals [PDF]
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

Tracing the evolutionary pathway: on the origin of mitochondria and eukaryogenesis. [PDF]
This study examines the stepwise transition from archaeal–bacterial associations to the emergence of eukaryotic cells. Metabolic cooperation and endosymbiosis fostered ecological and genetic integration, with extensive gene transfer reshaping host biology.

Eukaryogenesis, a syntrophy affair [PDF]
Eukaryotes evolved from a symbiosis involving Alphaproteobacteria and archaea phylogenetically nested within the Asgard clade. Two recent studies explore the metabolic capabilities of Asgard lineages, supporting refined symbiotic metabolic interactions that might have operated at the dawn of eukaryogenesis.

Asymmetric metabolic adaptations undermine stability in microbial syntrophy. [PDF]
Abstract Syntrophic interaction, driven by metabolite exchange, is widespread within microbial communities. However, co-inoculation of most auxotrophic microorganisms often fails to establish a stable metabolite exchange relationship. Here, we engineered two auxotrophic Escherichia coli strains, each dependent on the other for essential ...

Syntrophy in anaerobic global carbon cycles [PDF]
Syntrophy is an essential intermediary step in the anaerobic conversion of organic matter to methane where metabolically distinct microorganisms are tightly linked by the need to maintain the exchanged metabolites at very low concentrations. Anaerobic syntrophy is thermodynamically constrained, and is probably a prime reason why it is difficult to ...

Eukaryogenesis: Did an Oxidative Crucible Result in Misleading Bioinformatic Analyses? [PDF]
Recently, Nature published a timed gene duplication analysis favoring gradual models for eukaryogenesis. However, high initial mutation rates due to endogenous ROS formation by the OXPHOS system of the future mitochondrion and ensuing positive selection for countermeasures might strongly inflate branch lengths in such analyses. Ruling out symbiogenesis

Genesis of ectosymbiotic features based on commensalistic syntrophy. [PDF]
Abstract The symbiogenetic origin of eukaryotes with mitochondria is considered a major evolutionary transition. The initial interactions and conditions of symbiosis, along with the phylogenetic affinity of the host, are widely debated.

Steady-State Anaerobic Co-Digestion of Aqueous Condensate From Municipal Sludge Pyrolysis. [PDF]
Anaerobic digestion of aqueous pyrolysis liquid (APL) was achieved despite its toxicity challenges. Optimal retention time, loading and acclimated inoculum improved APL conversion to methane. APL ozonation enhanced methane production, reaching 98% of theoretical yield.

Complete genome sequence of Syntrophobacter fumaroxidans strain (MPOB(T)). [PDF]
Syntrophobacter fumaroxidans strain MPOB(T) is the best-studied species of the genus Syntrophobacter. The species is of interest because of its anaerobic syntrophic lifestyle, its involvement in the conversion of propionate to acetate, H2 and CO2 during ...
