Selection, conservation and exploitation of biodiversity of yeasts microbiota from viticultural regional areas

2019-01-20

Contract:

ing authority: Minister of Agriculture and Rural Development of Romania

Period of realization of the project: 11.10.2019-10.12.2022

Project coordinator: The Research and Development Institute for Viticulture and Vinification Valea Calugărească

IBA budget: 60,000 lei

Project objective: Maintaining and managing diversity, in different conditions, as well as the dynamic of the yeast microbiota in relation to the sensory quality of the wine.

Specific objectives:

1. Evaluation of various information of the native genofound of yeasts of vinification:

        • Updating the database regarding the selection of valuable yeasts of national level vinification
        • Taxonomic and identification loading studies of vinification yeasts
        • Reactivation of the oenological yeast strains existing in the collections

2. Evaluation of the metabolic and oenological performances of the yeast strains under growing conditions

  • Laboratory testing for cell viability:
  • Qualitative screening for highlighting the extracellular activity
  • Metabolic characterization of vinification yeasts
  • Making single, double and / or sequential yeast cultures depending on the enzymatic and metabolic characteristics of the strains.

3. Testing the strains selected at the level of micro-vinification and physico-chemical and organoleptic analyzes for the obtained wines:

  • Obtaining red and white wines with the help of selected strains
  • Processing of the grapes and obtaining some local musts;
  • Reactivating the strains of interest and preparing the inoculum
  • Seeding the yeast strains at the pilot level and supervising the fermentation
  • Physico-chemical and organoleptic analysis of oblique wines (Compositional profile; Sensory profile of wines)

4. Creation of collections of Levurian germplasm at national level:

  • An accomplishment of a national collection with the local species of Saccharomyces and non-Saccharomyces.

5. Promoting and disseminating the results obtained:

        • Large-scale dissemination through national communication and publication of the result;
        • Participation in technical-scientific events in specific project areas (round tables, national/international symposiums, workshops);
        • Working visits / changes of good practice.
