Abstract:
Terpene profile of Muscat wines fermented by Saccharomyces species and hybrid yeasts was investigated. The amount of geraniol decreased in most wines with respect to the initial must except for Saccharomyces bayanus wines. On the other hand, alpha-terpineol amount was higher in wines fermented by Saccharomyces cerevisiae and hybrid yeasts. The amount of linalool was similar in all wines and comparable to the amount in the initial must. Lower levels of beta-D-glucosidase activity were found in the hybrid yeasts with respect to S. cerevisiae. Moreover, no relationship between beta-D-glucosidase activity and terpenes profile in Muscat wines fermented with Saccharomyces species and hybrids was found. Growth of yeasts on minimum medium supplemented with geraniol showed bioconversion of geraniol into linalool and alpha-terpineol. Percentages of geraniol uptake and bioconversion were different between Saccharomyces species and hybrids. Strains within S. bayanus, Saccharomyces kudriavzevii and hybrids showed higher geraniol uptake than S. cerevisiae, whereas the percentage of produced linalool and alpha-terpineol was higher in S. cerevisiae and hybrid yeasts than in S. bayanus and S. kudriavzevii. The relationship between geraniol uptake and adaptation of Saccharomyces species to grow at low temperature is discussed.
