Figure 2.
Flocculation level of parental (F6789), haploid (F6789A), transformants (F6789A-Δflo1 F6789A-Δflo5) and V5 strains. V5 is a laboratory haploid yeast derivative from a strain isolated from Champagne. This yeast was previously used as negative control for flocculation (Bidard et al.45) and we are sure that it has no adhesive properties. Flocculation was determined in YNB + glucose (2% w/v) (A), in YEPD (B) and in synthetic must (C). (D) Sedimentation without CaCl2 of non-flocculent strain V5 and F6789A-Δflo5. The data reported are mean values for triplicates. Vertical error bars represent standard deviations.
