Identification of probiotic bacteria in cosmetic creme using PCR technique
Folwarczná, Tereza ; Langová, Denisa (referee) ; Smetana, Jan (advisor)
Probiotic bacteria are found in a wide range of food products and their internal use brings many positive effects for the human body. Thanks to these benefits, probiotic bacteria began to be used in the cosmetic industry with the assumption of similar positive effects as with internal administration. The aim of this bachelor's thesis was the theoretical part, which was devoted to various genera of probiotics, which are most often used in cosmetic products, in which skin diseases, surface probiotics are most often used and what effect they bring in treatment. Subsequently, the most commonly used molecular-biological methods for the identification of probiotic bacteria were described. In the experimental part, the DNA of probiotic bacteria declared by the manufacturer was isolated from two cosmetic creams and subsequently their presence was verified using the polymerase chain reaction method.

Use of advanced molecular biology techniques for detailed characterization of probiotic bacteria from a dietary supplement
Folwarczná, Tereza ; Trachtová, Štěpánka (referee) ; Smetana, Jan (advisor)
The aim of the diploma thesis was the identification of probiotic bacteria from a probiotic food supplement in the form of syrup. DNA was isolated from the complex matrix of the product in sufficient purity and quality suitable for the real-time PCR method followed by PCR-HRM. Specific primers for the genera Lactobacillus, Bifidobacterium and Streptococcus and at the species level for the species Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus plantarum, Lactobacillus reuteri, Bifidobacterium animalis, Bifidobacterium breve, Bifidobacterium bifidum, Bifidobacterium lactis, Bifidobacterium longum, Bifidobacterium infantis and Streptococcus thermophilus were used for amplification by real-time PCR and PCR-HRM. After optimizing the conditions for specific primers, all declared bacteria were detected in the product.
