Abstract—

The ecological and taxonomic study of yeast communities of vineyards in Dagestan has demonstrated significant differentiation of species diversity depending on the type of substrate and plant ontogenesis. Thirty-three out of 44 yeast species were isolated from grape berries during the long-term study of this biotope. The seasonal occurrence of yeasts in agrocoenoses is characterized by the maximum species richness during ripening of grapes in late summer and in autumn. Each stage of plant development is characterized by a specific type of yeast population, which determines the possibility of isolating yeast species from plants and the underlying soils. The DNA fingerprinting method used for Saccharomyces cerevisiae strains isolated from the vineyards of Dagestan showed their high genetic heterogeneity.

达吉斯坦葡萄园的酵母菌群落：生态，分类和遗传特征

摘要—

对达吉斯坦葡萄园的酵母菌群落的生态学和分类学研究表明，取决于底物类型和植物本体形成，物种多样性具有显着差异。在对该生物群落的长期研究中，从葡萄浆果中分离出44种酵母菌中的33种。农用酶中酵母的季节性出现的特征是夏末和秋季葡萄成熟期间的最大物种丰富度。植物发育的每个阶段均以特定类型的酵母菌群为特征，这决定了从植物和下面的土壤中分离出酵母菌种的可能性。从达吉斯坦（Dagestan）葡萄园中分离出的酿酒酵母（Saccharomyces cerevisiae）菌株所用的DNA指纹图谱显示了其高遗传异质性。
