Tairov Institute of Viticulture and Wine-making" popup.description2 In the three largest microbial gene banks in the world, which contain yeast cultures, the strains of Ukrainian wine yeast was deposited (up to 73 samples). The population structure of Saccharomyces cerevisiae was analyzed using biochemical and DNA methods. The heterogeneity of the taxonomic composition of the grape yeast microflora (on the morphological elements of grapes and berries) and the dominance of the family Saccharomycetaceae are shown. The peculiarities of the population structure of wine yeast in relation to morphophysiological and biochemical characteristics have been studied. Among the biochemical parameters, the activity of enzymes that catalyze the reactions of plastic and energy metabolism, as well as the content of organic acids was studied. The biggest differences were found in the level of activity of enzymes of energy metabolism. Product Description popup.authors Karastan Olga M Papina Olena S popup.nrat_date 2021-02-12 Close
