Yeasts of the vineyards in Dagestan and other regions

摘要

Long-term studies of yeast species diversity in the vineyards of the Republic of Dagestan using various isolation techniques and various substrates in the vertical tier dynamics revealed 38 species. The most diverse species complex including 80% of the isolated species was formed on the berries. A list of 160 yeast species isolated from grapes, spontaneously fermented fresh juice, and other vineyard substrates was compiled using the results of the present work and the literature data on yeast occurrence. Analysis of generalized data revealed considerable similarity in the taxonomic composition of yeasts from different countries and continents and made it possible to shift from the genus to the species characterization of the grape-associated yeast community.
