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

Harnessing microbial power to degrade hydrocarbon‐based plastics

mLife, Volume 5, Issue 3, Page 263-281, June 2026.
Abstract The growing global plastic waste crisis demands the development of urgent, effective, and sustainable solutions. While conventional recycling methods present intrinsic limitations, microbial biodegradation of plastic waste has emerged as a promising alternative.

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.

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

Effects of Temperature on Mercury Methylation and Demethylation in Boreal Wetland Soils

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Wetlands are critical sites for methylmercury (MeHg) production, a neurotoxin that bioaccumulates in organisms and biomagnifies in aquatic food webs. Net MeHg production in wetland soil depends on the balance between microbially mediated MeHg production and the degradation of MeHg through both microbial and abiotic pathways.

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.

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).
