Abstract

Flor yeasts are Saccharomyces cerevisiae strains noted by their ability to create a type of biofilm in the air–liquid interface of some wines, known as ‘flor’ or ‘velum’, for which certain proteins play an essential role. Following a proteomic study of a flor yeast strain, we deleted the CCW14 (covalently linked cell wall protein) and YGP1 (yeast glycoprotein) genes—codifying for two cell surface glycoproteins—in a haploid flor yeast strain and we reported that both influence the weight of the biofilm as well as cell adherence (CCW14).
