Non-traditional foods containing probiotic bacteria
Sobotková, Markéta ; Konečná, Jana (referee) ; Trachtová, Štěpánka (advisor)
Probiotic microorganisms are contained in common dairy products as well in unconventional probiotic products consumed especially in Asian countries. In the thesis is shown overview of chosen less common foodstuffs containing probiotic microorganisms, which no belong to fermented dairy products. In the thesis are discussed positive health benefits of probiotics foodstuffs on the host. The experimental part deals with the identification of probiotic microorganisms, which are contained in chosen probiotic product from Asia. DNA was isolated from the product by use phenol extraction and using magnetic particles. Probiotic microorganisms in chosen product were detected using method real-time polymerase chain reaction (qPCR).

Real-time PCR and it´s use in food processing
Tomanová, Barbora ; Pravečková, Martina (referee) ; Trachtová, Štěpánka (advisor)
Polymerase chain reaction (PCR) is a method abundantly used in molecular diagnostics. PCR in real time or quantitative PCR (qPCR) is one of its modifications and thanks to its advantages it finds still wider utilization nowadays. It finds its use in the food-processing industry too with relatively precise detection, identification, and qualification of both desirable and undesirable components in food, which often brings considerable difficulties and leads to an intensive development of this method. In the experimental part a DNA was isolated from dairy product Bio Via Natur drink for its further processing by means of PCR and gain more detailed information about a bacterial composition using real-time PCR and HRM analysis.
