Eukaryogenesis From FECA to LECA: Radical Steps Along the Way

BioEssays, Volume 47, Issue 11, November 2025.
How did the last eukaryotic common ancestor (LECA) population evolve? Recent evidence shows an Asgard archaeon‐like organism acquiring a bacterium, the future mitochondrion, going from symbiosis to endosymbiosis. I postulate that almost all salient LECA characteristics could have resulted from the ensuing enhanced ATP generation and internal reactive ...

Database Release: PPSDB, a Linked Open Data Knowledge Base for Protist–Prokaryote Symbioses

Journal of Eukaryotic Microbiology, Volume 72, Issue 6, November/December 2025.
ABSTRACT As the ecological and evolutionary importance of symbiotic interactions between protists (microbial eukaryotes) and prokaryotes (bacteria and archaea) is better appreciated, keeping an overview of their diversity and the literature becomes a growing and ongoing challenge.

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 ...

From Low‐Loaded Mesophilic to High‐Loaded Thermophilic Anaerobic Digestion: Changes in Reactor Performance and Microbiome

Microbial Biotechnology, Volume 18, Issue 10, October 2025.
During the startup of a thermophilic anaerobic digester fed with sewage sludge, changes in reactor function were associated with changes in microbial community composition. The functional potential of the microbiome during different reactor stages was analyzed using genome‐resolved metagenomics.

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
