Saccharomyces cerevisiae strains, commonly used in Vermentino grape must fermentation, were entrapped in polyaldehyde-hardened gelatin discs by obtaining three different types of immobilizates which were assayed for fermentative activity. The cells immobilized as a biofilm produced more ethanol than normal, but cell release, although delayed, was not prevented, not even by coating the discs with an additional gel layer.
