Možnosti ovlivnění mikrobiologické čistoty potravin pomocí léčivých rostlin
Havelková, Lucie
Object of this thesis was to observe the microbiological purity of the juice and possible influence on purity by using extracts from selected species of medicinal, aromatic and culinary plants (MAPs). Presence of groups of Clostridium, Bacillus, E. coli, Enterococcus, Pseudomonas, molds and yeasts, psychrotrophic microorganisms and the total bacterial count was evaluated. Extracts of these kinds of plants were added to opened juice containers: fennel (Foeniculum vulgare var. dulce, L.), chamomile (Matricaria recutica, L.), hop (Humulus lupulus L.) and caraway (Carum carvi L.). Very good results after adding the extracts were achieved in growth restriction of groups of Clostridium, Bacillus, E. coli, Enterococcus and Pseudomonas. The extracts did not affect the growth of psychrotrophic microorganisms, molds and yeasts.

Functionalized hyper-cross-linked porous polyacetylenes
Havelková, Lucie
An atom-economic one-step chain-growth coordination homopolymerization providing high yields of functionalized hyper-cross-linked polyacetylenes with permanent micro/mesoporous texture and specific surface area up to 1062 m2 /g was introduced and optimized. Substituted 1,3-diethynylbenzenes served as monomers simultaneously providing functionalization and hyper-cross-linking of the networks. The homopolymerization was compatible with the heteroatom groups of the monomers and allowed to prepare polyacetylene networks with the wide spectrum of univalent functional groups: -F, -Cl, -Br, -NO2, -COOCH3, -CH2OH, -COOH and -CH=O decorating the aromatic segments of the networks in a high extent (7.87 mmol/g). A novel two-step synthesis of functionalized hyper-cross-linked polyacetylenes was introduced combining chain-growth coordination polymerization of acetylenic monomers and covalent templating using acetal and Schiff base protecting groups. By postpolymerization hydrolytic removal of the protecting segments from the primary networks, the networks with a high content (up to 9.61 mmol/g) of univalent functional groups -CH2OH, -CH=O and -NH2 were prepared. These groups were placed either on the cross-linking or linear (aromatic and aliphatic) network segments, even in the vicinity of the main...

Preparation of functionalized polyacetylenes with linear and cross-linked architecture
Havelková, Lucie ; Sedláček, Jan (advisor) ; Balcar, Hynek (referee)
The phenylacetylene type monomers with benzene ring substituted with one or two aldehyde groups (besides an ethynyl group) were efficiently polymerized into linear mostly high-molecular-weight polyacetylenes with aldehyde groups in pendants if the complex [Rh(NBD)acac] was used as the polymerization catalyst. To achieve high yield and molecular weight of the polymer the positioning of the aldehyde group to meta position with respect to the ethynyl group was most appropriate. It was confirmed that polyacetylenes with aldehyde groups were modifiable by a reaction with p-toluidine under formation of Schiff base type pendant groups. 1,3-Diethynylbenzenes with various substituents in position 5 on the ring (R = H, F, Cl, Br, HCO, NO2, COOCH3) were efficiently polymerized with [Rh(NBD)acac] catalyst into microporous or micro/mesoporous polyacetylene networks that exhibited specific surface area from 311 to 1146 m2 /g. In the case of the networks with HC=O groups, the positive effect of these groups was confirmed on the capacity of the network in CO2 and methanol vapor capture. The composition and texture of the networks possessing HC=O groups were partly reversibly modifiable in reaction with p-toluidine.
