Effect of adding exogenous acyl homoserine lactone signal to Pseudomonas aeruginosa premature culture and prediction of signal binding domain in Rhamnolipids RhlA enzyme

Archives of Pharmaceutical Sciences Ain Shams University, 2022
The hierarchy of quorum sensing system plays a crucial role in Pseudomonas (P.) aeruginosa virulence and production of important industrial bacterial products like rhamnolipids and proteases.

Natural Lactone-Based Quorum Sensing Inhibitors Attenuate Virulence in Pseudomonas aeruginosa. [PDF]

Chem Biodivers
Targeting bacterial communication, lab‐generated lactones (Lx) inhibited biofilm formation and eliminated mature biofilms within 24–48 h. Lx treatment also suppressed pyocyanin and rhamnolipid production while downregulating rhlR expression, highlighting their promise as potent quorum‐sensing (QS) inhibitors and next‐generation antibiofilm therapeutics.

A Mesorhizobium japonicum quorum sensing circuit that involves three linked genes and an unusual acyl-homoserine lactone signal

mBio, 2023
Members of the genus Mesorhizobium, which are core components of the rhizosphere and specific symbionts of legume plants, possess genes for acyl-homoserine lactone (AHL) quorum sensing (QS).

An Unprecedented Medium-Chain Diunsaturated N-acylhomoserine Lactone from Marine Roseobacter Group Bacteria

Marine Drugs, 2018
N-acylhomoserine lactones (AHLs), bacterial signaling compounds involved in quorum-sensing, are a structurally diverse group of compounds. We describe here the identification, synthesis, occurrence and biological activity of a new AHL, N-((2E,5Z)-2,5 ...

Joining the bacterial conversation: increasing the cultivation efficiency of soil bacteria with acyl-homoserine lactones and cAMP

Microbiology Spectrum, 2023
Bacteria need to be isolated in pure culture to gain access to the wide array of interesting functions they conceal. This is challenging because they do not live in isolation but instead in communities where they actively communicate and interact with ...

N-acyl-homoserine lactone-mediated quorum-sensing in Azospirillum: an exception rather than a rule.

, 2006
Forty Azospirillum strains were tested for their ability to synthesize N-acyl-homoserine lactones (AHLs). AHL production was detected for four strains belonging to the lipoferum species and isolated from a rice rhizosphere.

Detection of Diverse N-Acyl-Homoserine Lactones in Vibrio alginolyticus and Regulation of Biofilm Formation by N-(3-Oxodecanoyl) Homoserine Lactone In vitro [PDF]

Frontiers in Microbiology, 2017
Quorum sensing (QS) is a cell-to-cell communication system based on the exchange of small intercellular signal molecules, such as N-Acyl homoserine lactones (AHLs), which act as cell-density mediators of QS gene expression, and are highly variable both in types and amounts in most Gram-negative Proteobacteria.

Diversity of N‐acyl homoserine lactone‐producing and ‐degrading bacteria in soil and tobacco rhizosphere [PDF]

Environmental Microbiology, 2005
Summary In Gram‐negative bacteria, quorum‐sensing (QS) communication is mostly mediated by N‐acyl homoserine lactones (N‐AHSL). The diversity of bacterial populations that produce or inactivate the N‐AHSL signal in soil and tobacco rhizosphere was investigated by restriction fragment length polymorphism (RFLP ...

Genome analysis of quorum sensing Cedecea neteri SSMD04 leads to identification of its novel signaling synthase (cneI), cognate receptor (cneR) and an orphan receptor [PDF]

PeerJ, 2015
Cedecea neteri is a very rare human pathogen. We have isolated a strain of C. neteri SSMD04 from pickled mackerel sashimi identified using molecular and phenotypics approaches. Using the biosensor Chromobacterium violaceum CV026, we have demonstrated the

Autonomous Control of Gene Expression Using Endogenous Transcription Signals

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Autonomous cell‐based control of heterologous gene expression can simplify batch‐culture bioprocessing by eliminating external monitoring and extrinsic control of culture conditions. Existing approaches use auto‐induction media, synthetic cell‐cell communication systems, or application‐specific biosensors.
