Figure 14 A novel NewFlo type flocculation gene. The flocculation gene isolated from S.
cerevisiae CCUG53310 was expressed constitutively in S. cerevisiae CEN.PK 113–7D. The
resulting flocculation was inhibited by mannose, maltose, glucose and sucrose, but not galactose.
This means that it exhibited a NewFlo phenotype. S. cerevisiae CCUG53310 on the other hand,
shows a Flo1 phenotype, with inhibition of flocculation only by mannose. [Westman et al.,
unpublished data.]
