Characterization of glycolytic activities from non-Saccharomyces yeasts isolated from Bobal musts.
A large number of non-Saccharomyces yeasts were isolated from grapes of Bobal variety and identified according to their physiological and molecular characteristics. The yeasts were tested to determine the presence of β-glucosidase, β-xylosidase, α-arabinosidase, and α-rhamnosidase activities and five isolates were selected. All enzymatic activities were induced by the presence of glycosides as the only carbon source in the medium, which seems to be a characteristic of the yeast isolate, and were characterized according to different parameters of enological interest.
