Impact of quorum sensing on the quality of fermented foods

Research output: Contribution to journalJournal articleResearchpeer-review

The quality of fermented food highly dependents on the microorganisms involved, their metabolic activities and interactions. Recently, focus has been on quorum sensing (QS) being a cell density-dependent mechanism allowing adaptive responses. Specific QS molecules in prokaryotes and eukaryotes, respectively, mediate the transcriptional changes. For food-borne microorganisms QS regulated traits include biofilm formation, acid stress tolerance, bacteriocin production, competence, adhesion, morphological switches and oriented growth. QS has been reported for microorganisms involved in the production of a number of different fermented foods such as fermented vegetables, sourdough, dairy products, wine, and so on suggesting that QS plays a role in the fermentation of these fermented foods.
