dc.description.abstract |
Yeasts are the most important microorganisms in wine production, and their number and diversity on grape berry
surfaces and stalk are influenced by grape variety, degree of grape maturity at harvest, climatic conditions, geographic
location, physical damage of grapes, the intensity of pest management etc.
This paper pursues two lines of research: isolation and purification of yeast strains responsible with the alcoholic
fermentation from vineyards Focşani and Bucium-Iaşi, and testing of the oenological characteristics of the isolated
yeast strains. Presented results represents a part of a project aiming selection of new yeasts strains from indigenous
flora, because they influence fermentation speed, wine flavor and other wine qualities. These informations are important
for wine-makers to produce wine with high quality and typical attributes. Yeast isolation and obtaining of the pure
cultures was done mainly through inoculums dissemination and loop exhaustion techniques on solid nutrient media.
Following isolation and purification a total of 15 yeasts strains were selected and further studied in the laboratory
regarding degree of foam production and alcoholic capacity. After the testing procedures, three yeasts strains were
retained for future research to optimize the fermentation processes and to obtain quality white wines from both
vineyards. Two yeasts strains (V0101, V2101) were originally from viticultural center Bucium Iaşi and one strain
(AC2) originates from viticultural center Focşani. |
