Three wine-making residues (grape seeds, skins and stems), and corn cobs were evaluated as support
material for immobilization of Saccharomyces cerevisiae and the ethanol production by the immobilized
cells was assessed. The main objective ofthis study was to find an abundant and low cost material suitable
for the cells immobilization and able to be used in a next step of wine production by immobilized yeast
cells.
