Genetic polymorphism of sherry Saccharomyces cerevisiae yeasts

Аннотация

The review deals with natural diversity of sherry (“flor”) Saccharomyces cerevisiae yeasts. Various properties of these yeasts are analyzed: life cycles, fermentation of sugars, sensitivity to methyl violet and killer toxins, and resistance to ethanol and sulfite. Special attention is paid to molecular identification and differentiation of sherry yeasts. The history of their nomenclature is considered, including the names of possible subpopulations: “aceti,” “beticus” (“cheresienses”), “cordubensis,” “gaditensis,” “hispanica” (“prostoserdovii”), and “oxidans.”
