Identification of wine yeasts by PCR-RFLP method
 Šuranská, Hana ; Vojtíšková, Marie (referee) ; Vránová, Dana (advisor)
This thesis deals with identification of the wine yeasts by applying the PCR-RFLP method. The identification and characteristic of the yeasts has gone through substantial changes in recent years. There have been introduced new methods of taxonomic classifying based on the molecular methods, which are oriented to easy and fast identification. One of these methods is the PCR-RFLP method. The amplification of the 5•8S-ITS rDNA sequence by the polymerase chain reaction with use of the primers ITS1 and ITS4 leads to the amplification of the specific sequence of DNA. Such multiplied DNA is after repurifying by the ethanol and drying submitted to the restriction analysis. With use of the restriction endonuklases DNA is chopped into the specific segments typical for the particular genus. The chopped fragments can be separated in the electric field in the agarose gel and subsequently evaluated. In this thesis together 63 type yeasts were used. These yeasts were analysed by applying of the seven restriction endonuklases – HaeIII, HhaI, HinfI, HpaII, TaqI, AluI a MseI. The final image of type yeasts splitting was compared to the results of splitting of already identified wine yeasts and these yeasts were subsequently taxonomically classified. Evaluation of genetic similarity was conducted by program BioNumerics and as the results the dendrograms that were created with use of Jaccard‘s coefficients are obtained.
