Quorum sensing signaling molecules produced by reference and emerging soft-rot bacteria (Dickeya and Pectobacterium spp.). [PDF]

PLoS ONE, 2012
BackgroundSeveral small diffusible molecules are involved in bacterial quorum sensing and virulence. The production of autoinducers-1 and -2, quinolone, indole and γ-amino butyrate signaling molecules was investigated in a set of soft-rot bacteria ...

Plant‐Derived Extracts Disrupt Biofilm Formation and Quorum Sensing in Yersinia enterocolitica: Insights From GC‐MS and Molecular Docking

Food Chemistry International, EarlyView.
The graphical abstract represents how natural plant products that preferentially target the specific receptors of quorum sensing could be developed to combat biofilms linked to Yersinia enterocolitica using the potent abilities of protein–ligand complexes with high docking scores.

Functional analysis of the Pseudomonas aeruginosa autoinducer PAI [PDF]

Journal of Bacteriology, 1996
A series of structural analogs of the Pseudomonas aeruginosa autoinducer [PAI, N-3-oxo-dodecanoyl homoserine lactone] were obtained and tested for their ability to act as autoinducers in stimulating the expression of the gene for elastase (lasB) by measuring beta-galactosidase production from a lasB-lacZ gene fusion in the presence of the ...

Identification of genes regulated by cold temperature - a study of mdtJI in E. coli O157:H7 [PDF]

, 2009
E. coli O157:H7, a serious food-borne pathogen, is capable of adapting to distinctly different environments, ranging from the ruminant, to soil and water.

Revisiting Burn Wound Infections: A Comprehensive Review on the Dual Potential of Phages and Probiotics Against Acinetobacter baumannii

Journal of Clinical Laboratory Analysis, EarlyView.
Effect Probiotics on immune system modulation and wound Healing. ABSTRACT Introduction Burn wound infections caused by Acinetobacter baumannii remain a critical clinical challenge due to its extensive multidrug resistance, particularly against carbapenems.

Survival and recovery of Escherichia coli O157:H7 during starvation at sub-optimal temperatures [PDF]

, 2014
Escherichia coli O157:H7 is an important foodborne pathogen with a dual lifestyle of growth within a host and persistence in non-host environments. Environmental survival of E.

Asymmetric autoinducer thresholds drive distinct intragenus and interspecies QS responses. [PDF]

, 2019
(A) CAI-1 produced by V. cholerae engages its cognate CqsS receptor at very low cell densities. In contrast, AI-2 does not accumulate to sufficient levels to engage its cognate LuxPQ receptor until much higher cell densities.

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Biosynthesis of autoinducer-2 as the possible mechanism to enhance decolourisation of Azo dye by citrobacter freundii A1 [PDF]

, 2012
In this study, we attempted to understand possible mechanism associated with bacterial azo dye decolourisation via mass spectral analysis and shotgun cloning of genomic DNA from C. freundii A1.

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐
