Lachmanová, Klára
This thesis is focused on the ability of identification of the Brettanomyces yeasts in wine by using molecular PCR methods. The microorganisms occurring in wine, their characteristics and properties are described here. It also focuses on the most common diseases of wine, which leads in many cases to depreciation till inedibility of the wine. The main part is about the isolation of DNA needed for further evaluation, and molecular techniques, focusing on the PCR. There are described the procedures for isolations and the methodology of PCR and its evaluation. The conclusion is focused on assays already performed detection of microorganisms, particularly Brettanomyces yeasts. There are evaluated for its speed, accuracy and reliability.
