Nutrient Inputs Stimulate Mercury Methylation by Syntrophs in a Subarctic Peatland

Frontiers in Microbiology, 2021
Climate change dramatically impacts Arctic and subarctic regions, inducing shifts in wetland nutrient regimes as a consequence of thawing permafrost. Altered hydrological regimes may drive changes in the dynamics of microbial mercury (Hg) methylation and

Community structure in methanogenic enrichments provides insight into syntrophic interactions in hydrocarbon-impacted environments

Frontiers in Microbiology, 2016
The methanogenic biodegradation of crude oil involves the conversion of hydrocarbons to methanogenic substrates by syntrophic bacteria and subsequent methane production by methanogens. Assessing the metabolic roles played by various microbial species in

Disentangling a metabolic cross-feeding in a halophilic archaea-bacteria consortium

Frontiers in Microbiology, 2023
Microbial syntrophy, a cooperative metabolic interaction among prokaryotes, serves a critical role in shaping communities, due to the auxotrophic nature of many microorganisms.

Evaluation of the Bioenergetic Potential of Marine Macroalgae in Anaerobic Digestion Systems

CLEAN – Soil, Air, Water, Volume 54, Issue 4, April 2026.
ABSTRACT This study evaluated the production of biogas by anaerobic digestion, using three groups of marine macroalgae: Chlorophytes (green), Phaeophytes (brown), Rhodophytes (red), and their mixture (GRB). The objective was to investigate how the composition of each group influences the production of biogas and methane, as well as the use of digestate

The Prebiotic and Techno‐Functional Potential of Microbial Exopolysaccharides for Human Health and Food Systems

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 2, March 2026.
ABSTRACT Microbial exopolysaccharides (EPS) represent a diverse class of biopolymers holding considerable promise as functional food ingredients. This review analyzes the dual function of microbial EPS as a candidate for prebiotic agents and techno‐functional additives.

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, Volume 13, Issue 10, 18 February 2026.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Metabolism and Occurrence of Methanogenic and Sulfate-Reducing Syntrophic Acetate Oxidizing Communities in Haloalkaline Environments

Frontiers in Microbiology, 2018
Anaerobic syntrophic acetate oxidation (SAO) is a thermodynamically unfavorable process involving a syntrophic acetate oxidizing bacterium (SAOB) that forms interspecies electron carriers (IECs).

Eukaryogenesis: Did an Oxidative Crucible Result in Misleading Bioinformatic Analyses?

BioEssays, Volume 48, Issue 2, February 2026.
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
