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.

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.

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.

Oxazaborolidine derivatives inducing autoinducer-2 signal transduction in Vibrio harveyi
Bioorganic & Medicinal Chemistry, 2008The bioluminescence of the marine bacterium Vibrio harveyi is controlled by quorum sensing. This effect is mediated by production, accumulation, and auto-detection of the species-specific autoinducer 1 (AI-1), autoinducer 2 (AI-2), and the V. cholerae autoinducer 1 (CAI-1). The V. harveyi AI-2 was recently identified as furanosyl borate diester.

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.

Bacterial Autoinducer-2 Detection via an Engineered Quorum Sensing Protein
Analytical Chemistry, 2015Autoinducer-2 (AI-2) is a Quorum Sensing (QS) molecule utilized by bacteria in interspecies communication. More recently, it is identified to be vital in regulating QS pathways in a number of human and foodborne pathogens. Methods to detect AI-2 in a rapid and highly sensitive manner can help in the early detection of bacterial infections.

Temporal regulation of enterohemorrhagic Escherichia coli virulence mediated by autoinducer-2
Applied Microbiology and Biotechnology, 2008The autoinducer-2 (AI-2) molecule is produced by many bacterial species, including various human gastrointestinal (GI) tract commensal bacteria, and has been proposed to be involved in interspecies communication. Because pathogens are likely to encounter AI-2 in the GI tract, we studied the effects of AI-2 on various phenotypes associated with ...

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.

Production, detection and application perspectives of quorum sensing autoinducer-2 in bacteria
Journal of Biotechnology, 2018Autoinducer-2 (AI-2) is a major signal molecule in bacterial quorum sensing (QS) besides N-acyl homoserine lactones (AHLs or AI-1). AI-2 mediated QS pathways have been proved to regulate gene expression and physiological behaviors of bacteria in either intraspecies or interspecies communication. Recent reviews have mainly summarized AI-2 structures, AI-

The Periodontopathogenic BacteriumEikenella corrodensProduces an Autoinducer-2-Inactivating Enzyme
Bioscience, Biotechnology, and Biochemistry, 2013Eikenella corrodens produces autoinducer-2 (AI-2) in the mid log phase, and AI-2 activity decreases dramatically during the stationary phase. We investigated the mechanism underlying this decrease in AI-2 activity. To analyze the mechanism, we extracted and purified AI-2 from the supernatant of mid-log-phase culture.
