Use of algae for production of biomass and bioproducts
Slonek, Jaroslav ; Máša, Vítězslav (referee) ; Brummer, Vladimír (advisor)
Submitted bachelor thesis is focused on description of use of algae for biomass and bioproducts production. The first part of the thesis is devoted to the taxonomic classification of algae and a basic summary of the characteristics of the different algal groups. The next part is aimed at bioproducts, which are obtained by algae cultivation and possibilities of further processing for energy purposes are also described. As for the cultivation, the emphasis is on modern methods in this area, i.e. on the possibility of using waste products in the culture process. In the next part, technological parameters of cultivation are discussed, for instance effects of technological parameters on growth and composition of biomass and production of desired products. The next chapter summarizes types of used culture bioreactors in which the growth of biomass occurs in a controlled environment. The information obtained and collected in the thesis is further discussed and summarized in the conclusion.

Usage of flue gas as a source of CO2 for algae cultivation in bioreactors
Slonek, Jaroslav ; Juřena, Tomáš (referee) ; Brummer, Vladimír (advisor)
This master`s thesis is focused on possibility of use of flue gas as source of CO2 for algae cultivation in bioreactors. The first part of the master`s thesis is devoted to a qualitative and quantitative description of flue gas sources as CO2 source for algae cultivation. In the thesis industry sectors with the largest share of CO2 emissions on a global scale and in the Czech republic are summarized. On the basis of these data it was possible to determine cheap sources of CO2 for algae cultivation producing valuable biomass and other bio-products. The composition of flue gas from these sources was discussed in this section also with given expected outlook within the following years. The next part of the thesis is devoted to the influence of flue gas properties on algae cultivation. The impact of flue gas individual parameters on cell growth rate, quality and composition of biomass is described there. The description and design of the bioreactor is processed in the next part of the thesis. The experimental part of the thesis was performed on a bioreactor with similar properties. The next part of the thesis describes the effect of light on algae cultivation and the design of a regulation scheme for bioreactor light source. The experimental part of the thesis describes methods used to determine the concentrations of flue gas substances that could pass from flue gas into cultivation medium for algae cultivation to measure the changing composition of the flue gas in the closed experimental bioreactor system. The processed data from experimental measurements are presented and are discussed. The change in the composition of the culture medium for algae (without the presence of algae) due to flue gas aeration was monitored in the experimental part. It includes also the measurement of the change in the composition of the flue gas in time. All obtained and collected information are then summarized and discussed in the final part of the master`s thesis.
