Evidence on the occurrence of direct interspecies electron transfer (DIET) during anaerobic digestion for the production of biomethane: A review

Science of The Total Environment
Anaerobic digestion is one of the most efficient technologies for the conversion of organic waste into biomethane which is a form of bioenergy. To have successful operation of the anaerobic digestion process, different studies have focused on its operational parameters, however, the efficient and stable operation of AD relies on syntrophic ...

A new model for electron flow during anaerobic digestion: direct interspecies electron transfer to Methanosaeta for the reduction of carbon dioxide to methane

, 2013
Anaerobic conversion of organic wastes and biomass to methane is an important bioenergy strategy, which depends on poorly understood mechanisms of interspecies electron transfer to methanogenic microorganisms.

Ecology and evolution of pyrazines in insects

Biological Reviews, Volume 101, Issue 4, Page 1937-1959, August 2026.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Co-occurrence of Methanosarcina mazei and Geobacteraceae in an iron(III)-reducing enrichment culture

Frontiers in Microbiology, 2015
Methanosaeta harundinacea and Methanosarcina barkeri, known as classic acetoclastic methanogens, are capable of directly accepting electrons from Geobacter metallireducens for the reduction of carbon dioxide to methane, having been revealed as direct ...

GcrR in Streptococcus mutans Inhibits the Morphological Transition of Candida albicans Through Ras1–cAMP/PKA Pathway in the Cross‐Kingdom Biofilms

Molecular Oral Microbiology, Volume 41, Issue 4, Page 188-200, August 2026.
ABSTRACT The dual‐species biofilms formed by Streptococcus mutans and Candida albicans exhibit enhanced cariogenic potential due to the production of extracellular polysaccharides (EPSs). The response regulator GcrR in S. mutans negatively regulates EPS synthesis, but its impact on dual‐species biofilms remains unclear.

Soybean‐Derived Exosome‐Like Nanovesicles Regulate Lipid Metabolism via Mitochondrial Biogenesis and UCP1/PGC‐1α Mediated Thermogenesis

Food Frontiers, Volume 7, Issue 4, July 2026.
Soybean‐derived exosome‐like nanovesicles suppress lipid accumulation of adipocytes via UCP1/PGC‐1α mediated thermogenesis pathway and boosting mitochondrial function. ABSTRACT Obesity has become an important public health concern in modern society. Plant‐derived exosome‐like nanovesicles are emerging as candidates for obesity intervention.

Syntrophic Growth of Geobacter sulfurreducens Accelerates Anaerobic Denitrification

Frontiers in Microbiology, 2018
Nitrate is considered as a contamination since it’s over discharging to water incurs environmental problems. However, nitrate is an ideal electron sink for anaerobic pollutant degraders desiring electron acceptors due to the high redox potential ...

Coumarins Disrupt Cell–Cell Communication and Virulence in Priority Pathogens: Targeting the PQS Signalling System in Pseudomonas aeruginosa

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
The selective nature through which coumarin compounds produced by different species of plants target PQS signalling in Pseudomonas aeruginosa and select for distinct phenotypic responses in key pathogenic organisms adds to the growing evidence of their utility as natural virulence suppressors. ABSTRACT Cell‐to‐cell communication in microbial systems is
