Environmental microbial communications in gram-positive and gram-negative bacteria [PDF]
Global Journal of Environmental Science and Management, 2023 Microorganisms are present in nature and shape an enormous a half of our micro- and macro-environment. Quorum sensing is the process of intercellular conversation that enables microbes to perceive their surroundings and change their behaviour, allowing ...

Molecular basis of quorum sensing signal-response systems in bacteria
Acta Biologica, 2017 Bacteria use quorum sensing (QS) to conduct gene expression programmes connected with collective behaviors. QS indicates on the capacity of bacteria to monitor their population density and regulate gene expression. QS activates from tens to hundreds of

Chemical Inhibition of Pyocyanin Biosynthesis Attenuates Virulence of Pseudomonas aeruginosa
Angewandte Chemie, EarlyView.Anti‐virulence strategies disarm pathogens rather than killing them directly. A β‐lactone reduces pyocyanin production without affecting growth. Chemical proteomics identified PqsC as the primary target via binding to Cys129. Crystallography revealed the binding mode, and SAR yielded a chloroacetamide inhibitor with improved enzymatic potency and anti ...

When all strains interact, partial privatization only favors QS if autoinducers are costless.
, 2022 (a) A schematic relationship of when all strains are simultaneously interacting. (b) With costless autoinducers, partial privatization favors QS. Selection equally favors AG and aG (yellow area) or Ag and ag (red area). Selection equally favors AG and aG

Chemical signalling within the rumen microbiome [PDF]
Animal BioscienceRuminants possess a specialized four-compartment forestomach, consisting of the reticulum, rumen, omasum, and abomasum. The rumen, the primary fermentative chamber, harbours a dynamic ecosystem comprising bacteria, protozoa, fungi, archaea, and ...
