Direct interspecies electron transfer enables anaerobic oxidation of sulfide to elemental sulfur coupled with CO2-reducing methanogenesis

iScience, 2023
Summary: Electric syntrophy between fatty acid oxidizers and methanogens through direct interspecies electron transfer (DIET) is essential for balancing acidogenesis and methanogenesis in anaerobic digestion.

Desulfovibrio‐Hydrogen Sulfide Mediates Capsaicin‐Induced Oxidative Stress and Gut Inflammation via TXNIP/NLRP3 Pathway

Food Bioengineering, EarlyView.
ABSTRACT The intake of capsaicin can disrupt the gut microecology and impact health, yet its underlying mechanism is not fully elucidated. This study, by establishing capsaicin‐induced human microbiota‐associated (HMA) mouse models revealed the molecular mechanism by which capsaicin perturbs the gut microbiota and metabolites, leading to intestinal ...

Mechanisms of Bacterial Extracellular Electron Exchange. [PDF]

, 2016
The biochemical mechanisms by which microbes interact with extracellular soluble metal ions and insoluble redox-active minerals have been the focus of intense research over the last three decades. The process presents two challenges to the microorganism;

Impact of conductive magnetite nanoparticles and anode polarization on glucose fermentation

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Electrically conductive materials and electrochemical stimulation strategies are increasingly explored to steer microbial fermentation towards desired metabolic outputs. These approaches also hold remarkable potential to couple wastewater treatment (WWT) to the production of value‐added compounds, in turn enhancing environmental ...

Metabolism Controls the Timing of Human Brain Development and Maturation

Journal of Inherited Metabolic Disease, Volume 49, Issue 3, May 2026.
ABSTRACT Among primates the human brain is the largest in size, exhibiting a higher neuronal density and connectivity. The prolonged expansion and subsequent connectome reorganization of the human brain have been suggested to promote higher cognitive and behavioral abilities.

The Role of Exopolysaccharides in Direct Interspecies Electron Transfer

Frontiers in Microbiology, 2022
Direct interspecies electron transfer (DIET) is an effective mechanism for microbial species to exchange electrons cooperatively during syntrophic metabolism. It is generally accepted that DIET is mainly mediated by electrically conductive pili and outer

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

ChemBioEng Reviews, Volume 13, Issue 2, April 2026.
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...

Direct Interspecies Electron Transfer Mediated by Graphene Oxide-Based Materials

Frontiers in Microbiology, 2020
Conductive materials are known to promote direct interspecies electron transfer (DIET) by electrically bridging microbial cells. Previous studies have suggested that supplementation of graphene oxide (GO) based materials, including GO, and reduced GO ...

Gut Luminal Exosomes in Young and Old Mice: Multi‐Omic Characteristics and Regulation of Gut Permeability

Aging Cell, Volume 25, Issue 4, April 2026.
This graphical abstract shows that gut luminal exosomes (LFEs) change with aging, with old mice producing LFEs that disrupt gut barrier integrity, alter microbiome composition, and promote insulin resistance. In contrast, LFEs from young mice improve gut barrier function and metabolic health, and transferring these LFEs can partially reverse age ...
