Commensalism and syntrophy in the chemostat: a unifying graphical approach
AIMS MathematicsThe aim of this paper is to show that Tilman's graphical method for the study of competition between two species for two resources can be advantageously used for the study of commensalism or syntrophy models, where a first species produces the substrate ...

Tracing the evolutionary pathway: on the origin of mitochondria and eukaryogenesis. [PDF]
FEBS JThis 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.

Syntrophy Goes Electric: Direct Interspecies Electron Transfer.
Annual Review of Microbiology, 2017 Direct interspecies electron transfer (DIET) has biogeochemical significance, and practical applications that rely on DIET or DIET-based aspects of microbial physiology are growing. Mechanisms for DIET have primarily been studied in defined cocultures in which Geobacter species are one of the DIET partners. Electrically conductive pili (e-pili) can be

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.

Engineered methanotrophic syntrophy in photogranule communities removes dissolved methane
Water Research X, 2021 The anaerobic treatment of wastewater leads to the loss of dissolved methane in the effluent of the treatment plant, especially when operated at low temperatures. The emission of this greenhouse gas may reduce or even offset the environmental gain from energy recovery through anaerobic treatment. We demonstrate here the removal and elimination of these

Steady-State Anaerobic Co-Digestion of Aqueous Condensate From Municipal Sludge Pyrolysis. [PDF]
Water Environ ResAnaerobic 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.

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.

Syntrophy in anaerobic global carbon cycles [PDF]
Current Opinion in Biotechnology, 2009 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 ...

Enhancing methane production from food waste fermentate using biochar. The added value of electrochemical testing in pre-selecting the most effective type of biochar [PDF]
, 2017 Background: Recent studies have suggested that addition of electrically conductive biochar particles is an effective strategy to improve the methanogenic conversion of waste organic substrates, by promoting syntrophic associations between acetogenic and ...

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.
