The Syntrophy hypothesis for the origin of eukaryotes revisited [PDF]
Nature Microbiology, 2020 The discovery of Asgard archaea, phylogenetically closer to eukaryotes than other archaea, together with improved knowledge of microbial ecology, impose new constraints on emerging models for the origin of the eukaryotic cell (eukaryogenesis). Long-held views are metamorphosing in favour of symbiogenetic models based on metabolic interactions between ...

Eukaryogenesis, a syntrophy affair [PDF]
Nature Microbiology, 2019 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.

Genesis of ectosymbiotic features based on commensalistic syntrophy. [PDF]
Sci RepAbstract 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.

mBio, 2020 Microbial syntrophy is universal in nature, profoundly affecting the composition and function of microbiomes. We have recently reported data suggesting direct cell-to-cell interactions leading to electron and material exchange between the two microbes in

Addition of Conductive Materials to Support Syntrophic Microorganisms in Anaerobic Digestion
Fermentation, 2022 Syntrophy and interspecies electron transfer among different microbial groups occurs in anaerobic digestion, and many papers recently reported their positive effect on biogas and methane production.

Syntrophy of aerobic and anaerobic ammonia oxidisers
Water Science and Technology, 2010 Deammonification is known as an efficient and resource saving sidestream process option to remove the nitrogen load from sludge liquors. The transfer of the intermediate product nitrite between both syntrophic groups of organisms – aerobic and anaerobic ammonia oxidizers (AOB) – appears very sensitive to process conditions such as temperature ...

Frontiers in Microbiology, 2016 Thermophilic methanogens are common autotrophs at hydrothermal vents, but their growth constraints and dependence on H2 syntrophy in situ are poorly understood.

Microbiome, 2019 Background In biogas plants, complex microbial communities produce methane and carbon dioxide by anaerobic digestion of biomass. For the characterization of the microbial functional networks, samples of 11 reactors were analyzed using a high-resolution ...

Interactive Film & Media Journal, 2023 While the gift economy is often considered a mechanism to strengthen social ties, the grift economy is often considered detrimental. However both systems rely on reciprocal play adding complexity to and questioning the ‘valuation’ mythology in contemporary free market logic.

Microorganisms, 2018 Abyssivirga alkaniphila strain L81T, recently isolated from a black smoker biofilm at the Loki’s Castle hydrothermal vent field, was previously described as a mesophilic, obligately anaerobic heterotroph able to ferment carbohydrates, peptides, and
