Microbial Small-Talk: Does Quorum Sensing Play a Role in Beer Fermentation?
The underlying mechanisms of quorum sensing are discussed, with an emphasis on brewer's yeast, while insights into how cell density-dependent signaling could influence the commercial brewing industry are offered.
Quorum sensing mechanisms in fungi
The study of quorum sensing mechanisms in fungi may be useful to prevent fungal infections, and interesting for its exploitation in industrial biotechnology.
Transcriptional control of the quorum sensing response in yeast.
- BiologyMolecular bioSystems
This work predicts CAT8 and MIG1 as key transcriptional regulators that control the differential expression of the genes affected by aromatic alcohol communication and shows that the S. cerevisiae quorum sensing system is a recent evolutionary innovation and that the genes which are differentially expressed upon treatment with these molecules are distributed across the genome in a highly non-random manner.
A Bacterial Quorum Sensing Molecule Elicits a General Stress Response in Saccharomyces cerevisiae
- BiologyFrontiers in Microbiology
This study found that N-(3-oxodododecanoyl)-L-homoserine lactone from the opportunistic human pathogen Pseudomonas aeruginosa induces a remarkable stress response in yeast, and preliminary findings on the molecular basis for the recognition of C12 by the yeast are reported.
Can community-based signalling behaviour in Saccharomyces cerevisiae be called quorum sensing? A critical review of the literature.
- BiologyFEMS yeast research
It is concluded that there is a lack of evidence to support a specific signalling mechanism and a critical signal concentration of these behaviours in S. cerevisiae and thus these features require further investigation.
Role of quorum sensing and chemical communication in fungal biotechnology and pathogenesis
- BiologyFEMS microbiology reviews
The diverse chemical 'languages' used by different groups of fungi are analysed, their possible cross-talk and interkingdom interactions with other organisms, and the potential applications of these mechanisms in biotechnology and pathogenesis are discussed.
Quorum sensing activity in Ophiostoma ulmi: effects of fusel oils and branched chain amino acids on yeast‐mycelial dimorphism
- BiologyJournal of applied microbiology
The effects of branched‐chain amino acids as well as their fusel alcohols and fusel acids as quorum sensing molecules are examined to gain an understanding of quorum‐sensing activity in O. ulmi as it relates to yeast‐mycelium dimorphism control.
The Evolution of Quorum Sensing in Bacterial Biofilms
- BiologyPLoS biology
The model suggests that the observed variation in quorum-sensing behavior can be linked to the differing requirements of bacteria in chronic versus acute biofilm infections, and shows that the balance of competition within and among biofilms can be pivotal in the evolution of quorum sensing.
Monitoring of quorum-sensing molecules during minifermentation studies in wine yeast.
- BiologyJournal of agricultural and food chemistry
The separation, detection, and quantification of the putative quorum-sensing molecules 2-phenylethanol, tryptophol, and tyrosol have been optimized on a simple HPLC-based system and form the basis for detailed studies in kinetics and regulation of quorum sensing in yeast fermentation.
Biotechnological implications of filamentation in Saccharomyces cerevisiae
- Biology, EngineeringBiotechnology Letters
This review aims to highlight the main causes of filamentous growth in S. cerevisiae in its industrial setting with the purpose of stimulating additional studies within this field.

Quorum sensing in bacteria: the LuxR-LuxI family of cell density-responsive transcriptional regulators
- BiologyJournal of bacteriology
How the marine luminescent bacterium V. fischeri uses the LuxR and LuxI proteins for intercellular communication is reviewed and a newly discovered family of LuxRand LuxI homologs in diverse bacterial species is described.
Feedback control of morphogenesis in fungi by aromatic alcohols.
- BiologyGenes & development
A quorum signaling pathway that links environmental sensing to morphogenesis in Saccharomyces cerevisiae is described, which defines a quorum-sensing circuit that allows SacCharomyces to respond to both cell density and the nutritional state of the environment.
Quorum sensing: the power of cooperation in the world of Pseudomonas.
- BiologyEnvironmental microbiology
It is shown that quorum sensing is essential for the expression of a battery of virulence factors as well as for biofilm formation in P. aeruginosa and thus represents an attractive target for the design of novel drugs for the treatment of P. aerospace infections.
The sensing of nutritional status and the relationship to filamentous growth in Saccharomyces cerevisiae.
- BiologyFEMS yeast research
This review integrates current knowledge on nutrient sensing and signalling in S. cerevisiae and suggests how an integrated signalling network may lead to the establishment of a specific developmental programme, namely pseudohyphal differentiation and invasive growth.

Signal Transduction Cascades Regulating Fungal Development and Virulence
- BiologyMicrobiology and Molecular Biology Reviews
This analysis illustrates both how the model yeast S. cerevisiae can serve as a paradigm for signaling in other organisms and also how studies in other fungi provide insights into conserved signaling pathways that operate in many divergent organisms.
Quorum Sensing in the Dimorphic FungusCandida albicans Is Mediated by Farnesol
