The aim of this work was to isolate the Saccharomyces cerevisiae yeast from the surface of wine grapes of the Malverina and Sauvignon varieties. Isolated yeasts were identified by the PCR-RFLP method. 5,8S ITS rDNA was amplified using PCR and restricition endonucleases HaeIII, HhaI, HinfI and TaqI were used for the restriction analysis which followed. The results were processed by UPGMA cluster analysis using the BioNumerics programme. The dominant genus on the surface of the Malverina variety grapes was Brettanomyces/Dekkera, while on the surface of the Sauvignon grapes we found mainly yeasts of the Pichia genus. The Saccharomyces cerevisiae species was not isolated from any of the two grape varieties.
