Photobioreactor for cultivating Spirulina
Tomandl, Jiří ; Naď, Martin (referee) ; Lošák, Pavel (advisor)
This bachelor thesis addresses the issue of microalgae cultivation, specifically focusing on Spirulina, with the aim of designing a device for its efficient cultivation to produce fresh biomass intended for consumption. Spirulina is characterized by its high content of proteins, minerals, and antioxidants, making it known as a dietary supplement with numerous benefits. The thesis includes the design of a photobioreactor for home cultivation of Spirulina, considering efficiency, simplicity, and economic affordability. The work includes literature review, technical documentation, prototype construction, economic evaluation of the device and operational costs. The proposed photobioreactor enables the production of fresh spirulina at low cost, thus contributing to the wider availability of fresh spirulina to the general consumer. The proposed solution has the potential to increase awareness of the ecological and nutritional benefits of spirulina and to promote its use in households.

Influence of deposits on algae growth in a tubular photobioreactor
Vajaýová, Veronika ; Lošák, Pavel (referee) ; Naď, Martin (advisor)
The content of the theoretical part of this bachelor thesis is a description of the tubular pho-tobioreactors, comparison of the individual types of the cultivation devices, the fundamental parameters influencing the efficiency of biomass production, and problems of formation of deposits on the inner surface of the photobioreactor. The attention is focused on the effect of sediment formation on the growth of microalgae in the tubular photobioreactor. Since the sediments affect the resulting light intensity in the suspension in the tubes, this phenomenon is reflected in the overall cultivation efficiency and the biomass yield. The practical part presents the course of measurements performed in the vertical tubular photobioreactor designed for flue gas cleaning using the microalgae Chlorella pyrenoidos Chick (IPPAS C2). The aim was to solve the problem of foaming, which subsequently caused deposits in the system's tubes or other parts. To this end, two measures were tested: • the mechanical one in the form of a wire mesh, • the chemical one using sunflower oil. The measured values were the basis for determining the effect of deposits on light intensity and also served to evaluate the functionality of the tested measures.

Design and testing of a horizontal photobioreactor
Šuráň, Michal ; Máša, Vítězslav (referee) ; Lošák, Pavel (advisor)
The master’s thesis deals with a microalgae cultivation and construction of the test unit. The first section focuses on phototrophic cultivation of microalgae including design solutions of photobioreactors. The second section is devoted to research on the use of microalgae along with Carbon Capture technologies. The third part deals with the design and assembly of the horizontal tubular photobioreactor. The last section describes the measurement of the cultivation conditions and testing of the photobioreactor.
