The role of physicochemical interactions and FLO genes expression in the immobilization of industrially important yeasts by adhesion

Popis výsledku v původním jazyce

One of the industrially important qualities of yeast is their ability to adhere to solids. Therefore, the goal of this work was to predict and subsequently select yeast strains capable to adhere by using models. Three different industrial yeast strains (S. cerevisiae) were tested for their adhesion to spent grains. The cell adhesion energies were calculated according to three adhesion models. The best agreement between forecast and observation of the adhesion was achieved with the XDLVO theory. Despiteits relative comprehensiveness, the XDLVO theory does not take into account specific biochemical interactions. Consequently, additional understanding of the yeast adhesion mechanism was obtained by means of quantifying the expression of selected FLO genes. The presented approach provides tools to select the appropriately adhesive yeast strains and match them with solid supports of convenient surface properties in order to design immobilized biocatalysts exploitable in biotechnological pr
