Screening biologických aktivit vláknitých hub izolovaných z plástového pylu
TRMALOVÁ, Františka
The thesis traces the biological activity of microorganisms that have been obtained from the beach pollen of bees. Using the molecular biological methods, two species of fungi of Penicillium species have been detected, namely P. corylophilum and P. citrinum. Neither did it contain a bactericidal and fungicidal activity.
Optimalisation of DNA isolation from opium poppy plants and poppy products.
ZAHRADNÍK, Václav
The thesis deals with the evaluation of selected DNA isolation methods on the selected samples of poppy, to evaluation the quality and the quantity of isolated DNA and select methods, which could be used in the future for testing forgery poppy in the food. There are mentioned methods of isolation and methods of evaluation in the literature research. The methodology is focused on isolation using kits and conventional methods (CTAB-PVP), evaluation of obtained samples by spectrophotometric measurement and PCR reaction followed by gel electrophoresis. It is obvious from the results that classical CTAB-PVP methods modified for plants appear to be the best methods. However, I do not recommend these methods because of the difficulty at work and I am inclining towards the company-supplied kits I have tested.
Vliv působení trávicího procesu zavíječe voskového (Galleria mellonella) na spory původce moru včelího plodu (Paenibacillus larvae).
MRÁZ, Petr
This diploma thesis deals with a serious honey bee (Apis mellifera) disease, the American foulbrood (AFB), and with possibilities of its control. The thesis is divided into two parts, the theoretical and the experimental. The theoretical part is written as a research and contains two big chapters. The first one describes American foulbrood disease and its causative agent, bacteria Paenibacillus larvae. The second part deals with the wax moth (Galleria mellonella). The experimental part then combines above mentioned themes in an effort to find the relationship between the wax moth caterpillars and bacteria P. larvae that could possibly help to control the AFB. The aim of this work was to determine whether the wax moth can disrupt resistant layers of P. larvae spores thanks to its well adapted digestive tract and whether it could change their germination.
