Study of Whey Biodegradation by thermophilic Bacteria
 Fischerová, Lenka ; Vránová, Dana (referee) ; Babák, Libor (advisor)
This thesis deals with the possibilities of biodegradation of whey by the means of a mixed thermophilic aerobic bacterial culture of the Bacillus and Thermus genera. After protein had been removed, the whey was used as a medium for cultivation of the thermophilic microorganisms. The cultivations took their course in a fermentation unit and in the Erlenmayer flasks in a heated shaker in a whey medium. The bioengineering characteristics of the cultivation processes and the degree of biodegradation of the whey were evaluated. Scale of the whey biodegration was judged through the analytical characteristics – concentration of biomass, laktose and a chemical oxygen demand (COD). A decrease of CHSK was detected in all cultivations. Maximal reduction of CHSK was happend always in c. first half of each exponential phase growt, i.e. about 15 ± 3 % after first growth phase and sumarily about 62 ± 4 % after second growth phase.
