Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

In vitro synthesis and biochemical characterization of acyl-homoserine lactone synthase and its deletion mutant.

PLoS ONE
Quorum sensing can induce density-dependent gene expressions that cause various problems. For quorum-sensing inhibition, fundamental solutions such as gene manipulation are required, and acyl-homoserine lactone synthase (AHL synthase), which synthesizes ...

Census of solo LuxR genes in prokaryotic genomes

Frontiers in Cellular and Infection Microbiology, 2015
luxR genes encode transcriptional regulators that control acyl homoserine lactone-based quorum sensing (AHL QS) in Gram negative bacteria. On the bacterial chromosome, luxR genes are usually found next or near to a luxI gene encoding the AHL signal ...

Natural Products Inhibit Bacterial Growth and Modulate Quorum‐Sensing Systems Las and Rhl in Pseudomonas aeruginosa PA14

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Quorum sensing (QS) is a bacterial cell communication system in Pseudomonas aeruginosa, which regulates the production of several virulence factors, including pyocyanin, exoproteases, and biofilm formation. Natural products (NPs) have demonstrated their ability to control QS in different bacteria. This work evaluated the antimicrobial and anti‐

Plant Growth‐Promoting Rhizobacteria and Bacterial Biocontrol Agents in Tomato Disease Management: Mechanisms, Applications, and Omics Perspectives

Global Challenges, Volume 9, Issue 12, December 2025.
Plant growth‐promoting rhizobacteria and bacterial biocontrol agents offer eco‐friendly alternatives to synthetic agrochemicals for tomato production. This review examines direct and indirect mechanisms that enhance growth and suppress pathogens, and highlights emerging omics tools that clarify plant–microbe interactions.

Quorum Sensing in Some Representative Species of Halomonadaceae

Life, 2013
Cell-to-cell communication, or quorum-sensing (QS), systems are employed by bacteria for promoting collective behaviour within a population. An analysis to detect QS signal molecules in 43 species of the Halomonadaceae family revealed that they produced ...

Unsaturated Fatty Acids Affect Quorum Sensing Communication System and Inhibit Motility and Biofilm Formation of Acinetobacter baumannii [PDF]

, 2018
The increasing threat of Acinetobacter baumannii as a nosocomial pathogen is mainly due to the occurrence of multidrug-resistant strains that are associated with the real problem of its eradication from hospital wards.

Altered Metabolism in Idiopathic Pulmonary Fibrosis

Journal of Cellular Physiology, Volume 240, Issue 12, December 2025.
ABSTRACT Idiopathic pulmonary fibrosis (IPF) is an incurable lung disease that ultimately terminates in death or lung transplantation. It is characterized by a restrictive pattern with impaired diffusion capacity, and typically presents with repeated acute exacerbations that result in permanent and progressive loss of respiratory function.

Long-distance communication in synthetic bacterial consortia through active signal propagation [PDF]

, 2018
A synthetic cell-cell signaling circuit should ideally be (1) metabolically lightweight, (2) insulated from endogenous gene networks, and (3) excitable rather than oscillatory or bistable.
