Analogs of the autoinducer of bioluminescence inVibrio fischer
Archives of Microbiology, 1986The enzymes for luminescence in Vibrio fischeri are induced only when a sufficient concentration of a metabolic product (autoinducer) specifically produced by this species accumulates. It has previously been shown that the autoinducer is 3-oxohexanoyl homoserine lactone and that it enters the cells by simple diffusion. To further study the mechanism of

Bacteroides species produce Vibrio harveyi autoinducer 2-related molecules
Anaerobe, 2005Quorum sensing is a density-dependent gene regulation mechanism that has been described in many bacterial species in the last decades. Bacteria that use quorum sensing as part of their gene regulation circuits produce molecules called autoinducers that accumulate in the environment and activate target genes in a quorum-dependent way.

Isolation of agr Quorum Sensing Autoinducers
2010Autoregulation of genes is often associated with quorum sensing systems where bacteria produce and secrete molecules that allow the cells to communicate with one another, leading to the activation of certain genes at certain population densities. Here we describe the identification of the agr as a quorum sensing system in Staphylococcus aureus and the ...

Involvement of ATP and autoinducer‐2 in aerobic granulation
Biotechnology and Bioengineering, 2009AbstractAerobic granulation represents an important bacterium‐to‐bacterium self‐immobilization process that has been exploited for the treatment of a wide spectrum of wastewaters, but the mechanism behind still remains unclear in a microbiological sense.

Inherent multistability in arrays of autoinducer coupled genetic oscillators
Physical Review E, 2007Rhythm generation mechanisms are very important for genetic network functions as well as for the design of synthetic genetic circuits. A significant attention to date has been focused on the synchronization of communicating genetic units, which results in the production of an unified rhythm.

Methods for Analysis of Bacterial Autoinducer‐2 Production
Current Protocols in Microbiology, 2005AbstractThe quorum‐sensing signal molecule autoinducer‐2 (AI‐2) is produced by over 50 diverse bacterial species and controls many different processes, including antibiotic production, biofilm formation, and virulence. AI‐2 production often varies according to growth phase, media conditions, and the presence of specific factors.

Functionality of Autoinducer Systems in Complex Environments
2014Cell-to-cell signalling via small diffusible molecules, usually termed quorum sensing (QS), represents a common behaviour in bacteria. This signalling regulates life style switches in many, if not most symbiotic microbial species either beneficial or pathogenic for their eukaryotic hosts, but is also involved in controlling environmental processes such

Assessing Pseudomonas aeruginosa Autoinducer Effects on Mammalian Epithelial Cells
2017The human mucosal environment in the gut is rich with interactions between microbiota and mammalian epithelia. Microbes such as the Gram-negative bacterium Pseudomonas aeruginosa may use quorum sensing to communicate with other microorganisms and mammalian cells to alter gene expression.
