Microfauna of the activated silt from the biological sewage disposal plant in Kroměříž region.
Hrudíková, Radka ; Illková, Kateřina (referee) ; Omelková, Jiřina (advisor)
Bachelor thesis deals with the description and evaluation of micro fauna of activated sludge biological sewage waste water in Kromeriz region. Furthermore, morphological description and evaluation of sludge flocs. The thesis describes the types of biota (biocenosis), which may occur in the activation tanks. There are also mentioned other incidental methods of sewage treatment such as mechanical, chemical and physicochemical methods. The experimental section describes the experiment procedure, apparatus and methods use for assessment of activated sludge. In the results the data are processed into the synoptic charts and the accompanying tables. At the end the results are evaluated.

Quantification of key genes in nitrification and denitrification
Chroňáková, Alica ; Čuhel, Jiří ; Radl, V. ; Elhottová, Dana ; Šimek, Miloslav
The objective of the study was to explore the long-term effect of cattle grazing activities on abundance of nitrifying and denitrifying communities on overwintering area. The abundances of studied populations were determined using qPCR method and copy numbers of .i.amoA, nirS,./i. and .i.nirK./i. genes were quantified in spring and fall. High input of cattle urine and excrements with other animal activities had a significant impact on abundance of nitrifying and denitrifying bacteria, being higher in cattle impacted soils in comparison to control. Our data also showed that abundance of both bacterial communities reflected seasonal changes.
