Abstract
The addition of an enzymatic preparation containing pectinase and beta (1 - -> 3) glucanase activities on yeast lees was tested in wine and a synthetic medium. We observed the hydrolysis of the macromolecules which were presen t initially in the medium and an acceleration of hydrolysis of cell wall gl ucans. The liberation of mannoproteins about 50 kDa was increased.
