Quorum sensing in Saccharomyces cerevisiae brewing strains: effects of 2-phenylethanol on proteomic, lipidomic, and metabolomic profile.

ABSTRACT: Quorum sensing (QS) is a known mechanism by which microbial populations adjust gene expression and coordinate community-wide social behaviors based on the proximate population density. This regulatory system has garnered significant interest in both scientific research and the food industry. However, a central question remains whether industrial strains of Saccharomyces cerevisiae, the yeast species predominantly utilized in brewing, employ quorum signalling mechanisms similar to those observed in laboratory strains and other fungi. Despite the potential relevance of microbial social behavior regulators to brewing practices, studies examining QS in Saccharomyces spp. are limited. In this investigation, three industrial brewing strains of S. cerevisiae were cultivated on SLAD (nitrogen-rest
