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 ...

Geobacter Strains Expressing Poorly Conductive Pili Reveal Constraints on Direct Interspecies Electron Transfer Mechanisms

mBio, 2018
Cytochrome-to-cytochrome electron transfer and electron transfer along conduits of multiple extracellular magnetite grains are often proposed as strategies for direct interspecies electron transfer (DIET) that do not require electrically conductive pili (

Nitric Oxide in Cancer: Mechanisms, Dual Role, and Therapeutic Strategies

MedComm – Oncology, Volume 5, Issue 3, September 2026.
Nitric oxide exerts concentration‐dependent dual roles in cancer, functioning as either a tumor promoter or suppressor. This review comprehensively examines NO's multifaceted regulation of tumor biology, including S‐nitrosylation signaling, metabolic reprogramming, immunemodulation, and therapy resistance, and highlights emerging therapeutic strategies

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 ...

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 ...

Comparative Phytochemical Profiles and Antioxidant Potential of Green and Variegated Morphotypes of Alternanthera bettzickiana Under Optimized Extraction Conditions

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Green and variegated Alternanthera bettzickiana morphotypes were compared after optimizing extraction (Box–Behnken design–RSM: 90% ethanol, 50°C, 2 h, 10 mg/mL). The green morphotype had higher phenolic content, FRAP, and ORAC activity, while the variegated morphotype had higher flavonoid and anthocyanin content.

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 ...

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.

High‐Salt Diet Links Gut Microbiota, Intestinal Barrier Function, and Macrophage Responses

European Journal of Immunology, Volume 56, Issue 7, July 2026.
This review examines how a high‐salt diet disrupts gut microbiota composition, impairs intestinal barrier integrity, and modulates macrophage function, with a focus on their interconnection along the gut‐liver axis. It highlights key methodological challenges, summarizes current mechanistic understanding, and identifies critical gaps for future ...
