Study of the role of the covalently linked cell wall protein within biofilm formation in a flor yeast strain

Flor yeasts are Saccharomyces cereuisiae 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 del...

Summary:Flor yeasts are Saccharomyces cereuisiae 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 (CCWI4). Keywords: flor yeast; flor biofilm; Ccwl4p; Ygplp; cell adherence; cell surface hydrophobicity
