In this study, the biodiversity and some interesting phenotypic properties of Saccharomyces wild yeasts isolated in distilleries, at least 100 years old, located in La Mancha (Spain), were determined. Strains were genetically characterized by RFLP-mtDNA, which confirmed a great genetic biodiversity with 73% of strains with different mtDNA profiles, highlighting the large variability found in sweet and fermented piquette substrata. The predominant species identified was S.

Article Synopsis
  • Stuck and sluggish fermentations in high-sugar grape musts are a major concern for winemakers and yeast producers, highlighting the need for effective yeast strains.
  • Developing yeast strains with both oenological and technological properties is challenging, and breeding programs focused on these traits are essential.
  • The study analyzed the behavior of 26 Saccharomyces cerevisiae wine strains under high-sugar conditions, revealing valuable characteristics that may aid in hybridization techniques for improved fermentation.

This work constitutes a preliminary study in which the capacity of non-Saccharomyces yeasts isolated from ancient distilleries as bio-control agents against moulds and in the treatment of waste waters contaminated by heavy metals-i.e. bio-remediation-is shown.
