Production, Characterization and Utilization of the Biomass from Various Sources
Gojkovic, Živan ; Vávrová, Milada (referee) ; Čertík, Milan (referee) ; Márová, Ivana (advisor)
Úprava biomasy je jedním z nejdůležitějších problémů v moderních přírodních vědách, protože je základní kategorií týkající se zemědělství, potravinářství, ekologie, zpracování odpadu a biotechnologie. Ať už živočišného, rostlinného nebo mikrobiálního původu, biomasa představuje obrovský zdroj surovin jako potravin, čistých chemikálií, bioaktivních molekul atd., jejichž izolace, charakterizace a formulace může vést k zajímavým novým produktům určeným pro lidskou spotřebu, nebo jako nový materiál v biomedicíně. Předložená studie byla zaměřena na výzkum dvou druhů biomasy - kuřecí kůže jako zdroje kolagenu t a biomasy mikrořasy Chlorella sorokiniana obohacené selenomethioninem (SeMet). V první části práce byl z kuřecí kůže izolován, identifikován a charakterizován kolagen typu I. Molekulární vlastnosti kuřecího kolagenu byly analyzovány a srovnány s jinými kolageny z živočišných kůží. Pro molekulární charakterizaci kolagenu byla použita viskosimetrie a ultrazvuková spektroskopie. Ultrazvukovou spektroskopií bylo zjištěno, že disagregace a zkapalňování hovězího kolagenu začíná při teplotě 40 °C, zatímco u kuřecího kolagenu začíná až při 50 °C. Viskosimetrie dále potvrdila vyšší tepelnou stabilitu kolagenu z kuřecí kůže, jeho denaturační teplota byla 50 °C, což je rovněž o deset stupňů více než u hovězího kolagenu. Kuřecí kolagen obsahuje dvakrát vyšší množství lysinu, což poskytuje tepelnou stabilitu kolagenu. Na základě získaných výsledků lze říci, že vzhledem ke své vysoké tepelné stabilitě a vhodnému aminokyselinovému složení, kuřecí kůže může být použita jako alternativní zdroj kolagenu typu I s aplikacemi v potravinářském průmyslu a biomedicíně. Druhá část práce byla zaměřena na obohacení biomasy zelené mikrořasy C. sorokiniana selenomethioninem. Experimentální část byla provedena v Laboratoři biotechnologie řas na Univerzitě Huelva ve Španělsku. Cílem první části experimentů bylo studovat vliv selenu na životaschopnost řas, morfologii buněk a akumulaci SeMet v biomase mikrořasy kultivované v dávkových kulturách. Subletální koncentrace Se v živném médiu, 40 mgL-1 (212 M), snížila rychlost růstu o 25 % ve srovnání s kontrolní kulturou. Hodnota EC50 45 mgL-1 (238,2 M) byla stanovena pro selenan. Ultrastrukturální studie ukazovaly na strukturální změny chloroplastu (granulární stroma, redukce thylakoid). Elektroforéza proteinů z biomasy mikrořasy ukazuje, že Se ovlivňuje expresi genu enzymu Rubisco. C. sorokiniana byla schopna akumulovat až 140 mgkg-1 SeMet během 120 h kultivace. Další část experimentální práce byla zaměřena na obohacování biomasy mikrořasy C. sorokiniana selenomethioninem během kontinuální kultivace s použitím 2,2 L bioreaktoru v kultivačním médiu s přídavkem koncentrace selenu v rozmezí od 5 do 50 mgL-1. C. sorokiniana rostla stejně ve všech testovaných koncentracích selenu kromě koncentrace 50 mgL1, která byla již po krátké době kultivace letální. Během kontinuální kultivace se 40 mgL-1 selenu, bylo získáno maximálně 246 gL-1 selenomethioninu denně. Výsledky ukazují, že kultivace v dávkových kulturách a dlouhodobá kontinuální kultivace mikrořasy C. sorokiniana pro získaní biomasy obohacené SeMet je možná pečlivým výběrem podmínek kultivace a subletálních koncentrací selenu v živném médiu.

Automatic Testing of JavaScript Restrictor Project
Bednář, Martin ; Pluskal, Jan (referee) ; Polčák, Libor (advisor)
The aim of the thesis was to design, implement and evaluate the results of automatic tests for the JavaScript Restrictor project, which is being developed as a web browser extension. The tests are divided into three levels - unit, integration, and system. The Unit Tests verify the behavior of individual features, the Integration Tests verify the correct wrapping of browser API endpoints, and the System Tests check that the extension does not suppress the desired functionality of web pages. The System Tests are implemented for parallel execution in a distributed environment which has succeeded in achieving an almost directly proportional reduction in time with respect to the number of the tested nodes. The benefit of this work is detection of previously unknown errors in the JavaScript Restrictor extension and provision of the necessary information that allowed to fix some of the detected bugs.

Web Search Engine of Pets Registration
Zaklová, Kristýna ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
The aim of this work was to design and create a web-based search engine that allows users to search for records of registered pets in real-time. The solution performs queries to all the available domestic registries in one easy step instead of manually searching them individually. Due to the high number of such services, people may not be aware of their existence. In such a case, they may not be able to find the owner of the animal. The presented solution provides an information system based on the Symfony framework. The system creates and sends HTTP requests to all the registries. The functionality and usability of the system were tested by automated tests and selected users who provided feedback. The main benefit of the system is its user-friendly user interface, which can be used by veterinary clinics, shelters, police, and other parties working with animals and looking up their registrations.

Investigation of Miniature Devices for Collection of Hydride Forming Elements in Atomic Spectrometry Methods
Krejčí, Pavel ; Čelechovská, Olga (referee) ; Janoš, Pavel (referee) ; Otruba, Vítězslav (referee) ; Dočekal, Bohumil (advisor)
Capability of a prototype of miniature collection device based on a strip of the molybdenum foil for collecting hydride forming elements (As, Se, Sb and Bi) was studied. The device was combined with a miniature hydrogen diffusion flame for detection by atomic absorption spectrometry. The conditions for trapping and subsequent vaporization of analytes of interest were optimized. A twin-channel hydride generation system was used for study of mutual interference effects of co-generated hydride forming elements. The influence of modification of the molybdenum surface with noble metals - Rh, Pt and Ir on trapping and vaporization processes was also studied and changes of microstructure of the foil surface after modification were investigated using scanning electron microscope equipped with energy dispersive x-ray analyzer and electron backscattered diffraction system. Complementary radiotracer and radiography experiments were performed in order to determine trapping efficiency and to assess the spatial distribution of collected analytes within the device. Practical application of the method was demonstrated on determination of antimony in water samples at trace level. Possibility of multi-element analysis was demonstrated by combining the collection device with atomization and excitation of the analyte in microwave induced plasma and with detection by atomic emission spectrometry method. The results of the experiments proved that tested miniature collection device is capable of trapping analytes that form volatile hydrides. This device can be coupled to various types of atomizers, typically used in spectrometry methods. Thus, very sensitive and specific detection of hydride forming elements can be performed.

Study of Generation, Trapping and Atomization of Hydride Forming Elements for Atomic Spectrometry
Furdíková, Zuzana ; Sommer, Lumír (referee) ; Čelechovská, Olga (referee) ; Řehůřková, Irena (referee) ; Dočekalová, Hana (advisor)
Interference effects of co-generated hydrides of arsenic, antimony, bismuth and selenium on trapping behavior of selenium or antimony hydrides (analytes) within iridium modified, transversely heated graphite tube atomizer (THGA) was investigated. A twin-channel hydride generation system was used for independent separate generation and introduction of analyte and interferent hydrides, i.e. in simultaneous and/or sequential analyte-interferent and interferent-analyte mode of operation. Influence of the analyte and modifier mass, interferent amount, trapping temperature and composition of the gaseous phase was studied. A simple approach for elimination of mutual interference effects by modification of the gaseous phase with oxygen in substoichiometric ratio to chemically generated hydrogen is proposed and suppression of these interference effects is demonstrated. A hypothesis on mechanism of trapping and mutual interference effects is drawn.
