| Description |
Batch cultures of a brewer's strain of Sacchavumyces ceveuisiae, NCYC 227, in a defined medium exhibited
characteristic flocculation during the late exponential phase of growth. However, early exponential cells were nonflocculent
and flocculation of such cells could not be induced even in the presence of Ca2+. A specific glycoprotein,
absent from the cell walls of non-flocculating exponentially growing cells of this yeast and those of non-flocculating
strains of S. cevevisiae, was identified on the cell wall surface of flocculating exponentially growing cells of S.
cerevisiae NCYC 227. Flocculent cells of S. cevevisiae NCYC 227 dispersed with EDTA and coated with
monovalent Fab portions of the antibody showed reduced flocculation. Removal of the monovalent antibody
portions from the cell surfaces induced cell flocculation in the presence of Ca2+. These results suggest a role for this
glycoprotein in yeast cell flocculation.
