Less usual technologies of biomass utilization
Červenáková, Jana ; Brázdil, Marian (referee) ; Baláš, Marek (advisor)
The main aim of the bachelor thesis is to elaborate less usual technologies of biomass utilization. In the first part of thesis are individual technologies described and divided. The second part of the bachelor thesis describes the concept of biomass and its specific featuress. The last part describes selected applications of less traditional technologies in the Czech Republic which produce electric power by using biomass fuel.

Thermotolerant strains application for preparation of selected metabolites on waste hydrolysates
Musilová, Kristína ; Vítová, Eva (referee) ; Babák, Libor (advisor)
This Bachelor´s Thesis deals with the preparation of the selected metabolite on hydrolysates of orange fruit waste, specifically on orange peel hydrolysates using thermotolerant strains. The thermotolerant Bacillus coagulans strain having lactic acid as the primary metabolite, a substance with a great perspective, was selected for the fermentation process for its exceptional properties. At the beginning of the experiment, optimal conditions for the growth of the selected microorganism were determined; these were applied during the fermentations. Several fermentations were performed under various conditions until those conditions were determined, in which lactic acid was produced. The fermentation production was determined by the HPLC method and the saccharide decrease by the Somogyi-Nelson method. To achieve lactic acid production, it was necessary to extract the orange peels by an organic agent before fermentation, in order to eliminate substances causing inhibition of micro-organism growth. Higher yields were achieved by the SHF method, but the highest by using the Lactobacillus casei strain.

Validation of probotic bacteria presence in fermeted plant food products
Péčiová, Bianka ; Fialová, Lenka (referee) ; Smetana, Jan (advisor)
Probiotic bacteria are an essential part of human nourishment which provide many health benefits. We consume them not only in traditional dairy fermented foodstuff, but also in the ever-expanding fermented plant products. The theoretical part summarized general knowledge about probiotic microorganisms, individual species used in technology of processing plant and dairy fermented products, and their influence on human health. The following chapters are devoted to various methods of identification of probiotic bacteria with emphasis on molecular diagnostics, specifically by PCR method. The experimental part is focused on the identification of lactic acid bacteria in a plant fermented product – in a fermented cabbage using 2 methods of isolation bacterial DNA and subsequent analysis by PCR method.
