Spatial Heterogeneity of Autoinducer Regulation Systems [PDF]
Sensors, 2012 Autoinducer signals enable coordinated behaviour of bacterial populations, a phenomenon originally described as quorum sensing. Autoinducer systems are often controlled by environmental substances as nutrients or secondary metabolites (signals) from ...

Differential effect of autoinducer 2 of Fusobacterium nucleatum on oral streptococci
Archives of Oral Biology, 2013Autoinducer 2 (AI-2) is a quorum sensing molecule and plays an important role in dental biofilm formation, mediating interspecies communication and virulence expression of oral bacteria. Fusobacterium nucleatum connects early colonizing commensals and late colonizing periodontopathogens. F.

Autoinducer-2 bioassay is a qualitative, not quantitative method influenced by glucose
Journal of Microbiological Methods, 2006Autoinducer-2 (AI-2) is a cell-to-cell signaling molecule which is thought to be utilized for quorum sensing processes by a variety of prokaryotic species. This molecule is usually detected using a so-called autoinducer bioassay, which relies on the ability of a Vibrio harveyi reporter strain to produce light in response to AI-2. However, as previously

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.

Methods for Analysis of Bacterial Autoinducer‐2 Production
Current Protocols in Microbiology, 2011AbstractQuorum sensing is a cell‐cell signaling process that many bacteria use to regulate gene expression as a function of the density of the population. This phenomenon involves the production, release, and response to small chemical molecules termed autoinducers.

Exogenous autoinducer-2 inhibits biofilm development of Desulfovibrio sp. Huiquan2017
World Journal of Microbiology and Biotechnology, 2021Sulfate-reducing bacteria (SRB) are culprits for microbiologically influenced corrosion, and biofilms are believed to play essential roles in the corrosion induced by SRB. However, little is known about the regulation of SRB biofilms. Quorum sensing signal molecules acyl-homoserine lactones (AHLs) and autoinducer-2 (AI-2) regulate biofilm formation of ...

Role of autoinducer-2 on the adhesion ability ofLactobacillus acidophilus
Journal of Applied Microbiology, 2009Lactobacilli adhere to the intestinal epithelium and this intimate association likely promotes retention in the gastrointestinal tract and communication with the immune system. The aim of this study was to investigate whether or not the quorum-sensing signalling molecule, autoinducer (AI)-2, was produced by Lactobacillus acidophilus and affected ...

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.

Developing a cell-based sensor for the detection of Autoinducer-2
SPIE Proceedings, 2013Abstract Bacteria use an intricate set of communi cation systems for sensing and interpreting environmental cues that coordinate population-based behavior. Quorum sensing is one of thes e systems, and it involves the production, release, and detection of small chemical signaling molecules.
