A total of 192 yeast isolates were obtained from completed fermentation of a mix of 'Malvasia delle Lipari' (92%) and 'Corinto nero' (8%) grapes in two wineries in Salina Island (Sicily, Italy). Fifty-one Saccharomyces spp. isolates were characterized using ITS-PCR, random amplified polymorphic DNA-PCR and mitochondrial DNA restriction fragment length polymorphism and 12 biotypes were identified. Representative strains of each biotype, tested for their physiological traits, exhibit different killer activity, fermentation vigour, production of hydrogen sulphide and show similar beta-glucosidase and proteolytic activity

Abstract
A total of 192 yeast isolates were obtained from completed fermentation of a mix of 'Malvasia delle Lipari' (92%) and 'Corinto nero' (8%) grapes in two wineries in Salina Island (Sicily, Italy). Fifty-one Saccharomyces spp. isolates were characterized using ITS-PCR, random amplified polymorphic DNA-PCR and mitochondrial DNA restriction fragment length polymorphism and 12 biotypes were identified. Representative strains of each biotype, tested for their physiological traits, exhibit different killer activity, fermentation vigour, production of hydrogen sulphide and show similar beta-glucosidase and proteolytic activityFile in questo prodotto:
