Multilevel Mechanisms of Magnetic Nanoparticles in Enhancing Dark Fermentative Hydrogen Production: From Pure to Mixed Cultures

Hydrogen
Dark fermentative hydrogen production is constrained by challenges including low hydrogen yield and operational instability. Magnetic nanoparticles (MNPs) have emerged as promising additives for enhancing biohydrogen production due to their unique ...

Mechanism for microbial population collapse in a fluctuating resource environment

Molecular Systems Biology, 2017
Managing trade‐offs through gene regulation is believed to confer resilience to a microbial community in a fluctuating resource environment. To investigate this hypothesis, we imposed a fluctuating environment that required the sulfate‐reducer ...

Rhizobacterial syntrophy between a helper and a beneficiary promotes tomato plant health

The ISME Journal
Microbial interactions impact the functioning of microbial communities. However, microbial interactions within host-associated communities remain poorly understood. Here, we report that the beneficiary rhizobacterium Niallia sp.

Pseudomonas aeruginosa Syntrophy in Chronically Colonized Airways of Cystic Fibrosis Patients [PDF]

Antimicrobial Agents and Chemotherapy, 2012
ABSTRACT Pseudomonas aeruginosa isolates from cystic fibrosis (CF) patients undergo remarkable phenotypic divergence over time, including loss of pigmentation, hemolysis, motility, and quorum sensing and emergence of antibiotic hypersusceptibility and/or auxotrophism.

Chemosynthetic Organic Matter Reveals a Protracted Episode of Past Methane Seepage Activities at a Newly Discovered Cold Seep Site (Mannar Basin) Off the East Coast of India

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Here, we present organic geochemical evidence of past methane‐seepage events in a sediment core retrieved from a recently discovered methane cold‐seep site off Mannar Basin, east coast of India. The significant negative C‐isotope excursion of organic matter (δ13CTOC) in the seep core compared to a reference non‐seep core suggests a substantial

Long‐Term Impact of the Largest Environmental Disaster in Latin America (Fundão Dam Failure) on Microbial Communities in Lakes of the Doce River Basin, Brazil

Environmental Microbiology, Volume 27, Issue 9, September 2025.
The collapse of the Fundão dam caused long‐term alterations in the microbiome of lakes in the Doce River basin, with microbial communities closely associated with heavy metals originating from the mining tailings. The findings also highlight potential microbial groups for biomonitoring and bioremediation efforts.

Direct cell-to-cell exchange of matter in a synthetic Clostridium syntrophy enables CO2 fixation, superior metabolite yields, and an expanded metabolic space.

Metabolic Engineering, 2019
In microbial fermentations at least 33% of the sugar-substrate carbon is lost as CO2 during pyruvate decarboxylation to acetyl-CoA, with the corresponding electrons lost in the form of H2. Previous attempts to reduce this carbon and electron loss focused

Anaerobic Digestion Performance and Microbial Community Structures in a Pilot‐Scale Up‐Flow Anaerobic Sludge Blanket (UASB) Treating Distillery Wastewater

Water Environment Research, Volume 97, Issue 8, August 2025.
This study demonstrates stable anaerobic treatment of high‐strength distillery wastewater in a pilot‐scale UASB reactor, achieving 86% COD removal and 75% methane yield at an OLR of 10.0 kg COD/m3/d. Microbial analysis highlights the role of syntrophic bacteria and hydrogenotrophic methanogens in enhancing performance under high OLR, offering insights ...
