Butyrate Conversion by Sulfate-Reducing and Methanogenic Communities from Anoxic Sediments of Aarhus Bay, Denmark

Microorganisms, 2020
The conventional perception that the zone of sulfate reduction and methanogenesis are separated in high- and low-sulfate-containing marine sediments has recently been changed by studies demonstrating their co-occurrence in sediments.

Comparative proteome analysis of propionate degradation by Syntrophobacter fumaroxidans in pure culture and in coculture with methanogens [PDF]

, 2018
Syntrophobacter fumaroxidans is a sulfatereducing bacterium able to grow on propionate axenically or in syntrophic interaction with methanogens or other sulfatereducing bacteria. We performed a proteome analysis of S. fumaroxidans growing with propionate

Metabolic Flexibility of Sulfate Reducing Bacteria

Frontiers in Microbiology, 2011
Dissimilatory sulfate-reducing prokaryotes (SRB) are a very diverse group of anaerobic bacteria that are omnipresent in nature and play an imperative role in the global cycling of carbon and sulfur.

Bacterial community analysis in upflow multilayer anaerobic reactor (UMAR) treating high-solids organic wastes [PDF]

, 2017
A novel anaerobic digestion configuration, the upflow multi-layer anaerobic reactor (UMAR), was developed to treat high-solids organic wastes. The UMAR was hypothesized to form multi-layer along depth due to the upflow plug flow; use of a recirculation ...

Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub‐Arctic Waterbodies in Northern Canada

Environmental Microbiology, Volume 27, Issue 12, December 2025.
Prokaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

Marine Cold Seep ANME‐2/SRB Consortia Produce Their Lipid Biomass From Inorganic Carbon

Environmental Microbiology, Volume 27, Issue 12, December 2025.
Lipid‐stable isotope probing (SIP) experiments in Astoria Canyon sediments revealed that both ANME‐2 and SRB primarily assimilate dissolved inorganic carbon (DIC or HCO3‐), not methane, into biomass. SRB‐specific lipids showed eightfold higher DI13C‐assimilation than ANME lipids, suggesting SRB directly assimilate DIC, while ANME assimilate an ...

Concerted Metabolic Shifts Give New Insights Into the Syntrophic Mechanism Between Propionate-Fermenting Pelotomaculum thermopropionicum and Hydrogenotrophic Methanocella conradii

Frontiers in Microbiology, 2018
Microbial syntrophy is a thermodynamically-based cooperation between microbial partners that share the small amounts of free energy for anaerobic growth.

Metagenomic Insights Into the Ecology, Taxonomy and Metabolic Capabilities of ‘Candidatus Darwinibacteriales’ Ord. Nov. (Formerly MBA03), a Potential Key Player in Anaerobic Digestion

Microbial Biotechnology, Volume 18, Issue 12, December 2025.
Metagenomic analysis of anaerobic digesters revealed a dominant, uncultured bacterial taxon—MBA03—now proposed as ‘Candidatus Darwinibacteriales’ ord. nov. This newly defined order includes potential syntrophic acetate‐oxidising bacteria (SAOB), suggesting a key role in methane production.

Beyond Methane Oxidation: The Protein Landscape of ANME‐2a Reveals an Integrated System for Diazotrophy and Membrane Fortification

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
A protein interaction network of ANME‐2a uncovers a modular blueprint where core methane oxidation is energetically coupled to nitrogen fixation and membrane lipid biosynthesis. This integrated system explains the archaeon's metabolic autonomy and resilience in its extreme deep‐sea niche.

Synthetic Escherichia coli consortia engineered for syntrophy demonstrate enhanced biomass productivity [PDF]

Journal of Biotechnology, 2012
Synthetic Escherichia coli consortia engineered for syntrophy demonstrated enhanced biomass productivity relative to monocultures. Binary consortia were designed to mimic a ubiquitous, naturally occurring ecological template of primary productivity supported by secondary consumption.
