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.
