Application of real-time PCR in microbiological analysis of food-stuffs
Novotná, Eva ; Michaela, Kotianová (referee) ; Španová, Alena (advisor)
Probiotic lactic acid bacteria of genus Lactobacillus play an important role in the digestive tract of human, e.g. protect against pathogenic microorganisms. Lactobacilli are often present in various food products. Lactic acid bacteria of the genus Lactobacillus can be detected by polymerace chain reaction (PCR) using specific primers LbLMA1 and R16. The bacterial DNA was isolated from Actimel Natur probiotic product by the phenol extraction method. DNA was amplified using real time PCR. Specific PCR products were detected using fluorescent intercalaction dye SybrGreen. The specific PCR products were verified by melting curve analysis (Tm 85°C) and by agarose gel electrophoresis (PCR products of 250 bp was amplified).
