Yeasts and wine
Palíková, Petra ; Vadkertiová, Renata (referee) ; Vránová, Dana (advisor)
This thesis deals with isolation and identification wine yeasts from grapes and must. For analysis was used white wine Sauvignon that was grown and producing after needs ecological agriculture. Remove samples were processed in laboratory and by the help of dilution method were obtained pure culture isolated yeasts. In the following step, by the application of commercial kit UltraCleanTM Microbial DNA Isolation Kit we were able to isolated individual DNA that it was used to the next analysis. Isolated DNA was amplification by PCR method with ITS1 and ITS4 primers. PCR products were detected on agarose gel. Amplification samples were chopped five restriction endonucleases: HaeIII, HinfI, TaqaI, AluI and MseI. Chopped DNA was detected by the same way as PCR products and it was compared with restriction patterns of collection yeasts. In the next step it was compared genetic similarity of isolated yeasts by using BioNumerics software. As a criterion it was used Pearson coefficients and UPGMA clastering analysis. The result is dedrogram of genetics similarity isolated yeasts.

L-ascorbyl-6-palmitate and its utilization in dietary and cosmetic supplements.
Palíková, Petra ; Zemanová, Jana (referee) ; Vránová, Dana (advisor)
Bachelor‘s thesis deals with the effection of antioxidants in foods and cosmetics supplements. Some antioxidants as vitamin A and beta-carotene, vitamin E and tocopherols and vitamin C as L-ascorbic acid and her derivate L-ascorbate-6-palmitate are described here. This derivate can by used as an accessory material in cosmetics and foods preparations, especially in the preparations that contain oil or fats, because as a lipophilic compound keeps them from getting rancid.
