FIG 3.

Sugar inhibition of flocculation. The amount of free cells in the presence of various sugars in different concentrations was measured by turbidimetry. (A) Weakly flocculating mutant. (B) Intermediately flocculating mutant. (C) Strongly flocculating mutant. The flocculation of all strains was inhibited by mannose and for the weakly flocculating strain to some degree also by various other sugars. Average values of duplicate experiments with duplicate technical replicates are shown with ±1 standard deviation (n = 2).
