This thesis explores the optimizing of the methods relevant to the cultivation, isolation, and identification of individual yeast strains from selected matrices, using the molecular biology methods. Grape berries, vine-leaves and soil from vineyard have been used as matrices. As yeasts are an integral part of fermentation processes, they are used for making of wine, the organoleptic charakteristics of which they influence. For identification of yeast strains the PCR-RFLP method has been used. Specifity of yeast DNA sequences of certain species has been used for this analysis. These spacers have been amplificated through the use of PCR and consequently they have been subjected to a restrictive analysis with specific restrictive endonucleases. These fragments have been detectioned through horizontal electrophoresis. In the literature background research section the basic informations about viticulture, yeasts, their cultivation and separation, PCR, restrictive analysis and horizontal electrophoresis is presented.
