ABSTRACT
AIMS:
The aim of this study was to identify the non-Saccharomyces yeast populations present in the grape must microflora from wineries from different areas around the island of Sicily. METHODS ANDRESULTS:
Yeasts identification was conducted on 2575 colonies isolated from six musts, characterized using Wallerstein Laboratory (WL) nutrient agar, restriction analysis of the amplified 5.8S-internal transcribed spacer region and restriction profiles of amplified 26S rDNA. In those colonies, we identified 11 different yeast species originating from wine musts from two different geographical areas of the island of Sicily.CONCLUSIONS:
We isolated non-Saccharomyces yeasts and described the microflora in grape musts from different areas of Sicily. Moreover, we discovered two new colony morphologies for yeasts on WL agar never previously described. SIGNIFICANCE AND IMPACT OF THE STUDY This investigation is a first step in understanding the distribution of non-Saccharomyces yeasts in grape musts from Sicily. The contribution is important as a tool for monitoring the microflora in grape musts and for establishing a new non-Saccharomyces yeast collection; in the future, this collection will be used for understanding the significance of these yeasts in oenology.
