Bachelor's thesis

Abstract:

This bachelor thesis deals with freshwater picocyanobacteria. The first part of it is focused on the occurrence of picocyanobacteria in the water reservoir Nýrsko and their penetration into the individual stages of technological treatment of drinking water in the water treatment plant Milence. The filter separation efficiency of picocyanobacteria in dependency on filter operational time and subsequently, the possible variants of optimalization or addition to the technological process for separation of picocyanobacteria from treated water are presented. The second part of this bachelor thesis deals with the use of picocyanobacteria in nanobiotechnology. It consists of pilot experiments with application of picocyanobacteria in addition with microwave synthesized magnetite for the nanobiotechnological application - sorption of the industrial dyes from water. For the preliminary tests, cultures of picocyanobacteria from the collections of the Hydrobiological institute of the Biology Centre of the Czech Academy of Sciences were tested. The continuous experiments were performed using a picocyanobacterial culture from the water reservoir Nýrsko. As the model pollutants the industrial dyes, Malachite green, Methylene blue, Rhodamine B, Crystal violet, were utilized.
