Utilisation of plant origin waste
Habáníková, Kamila ; Šťavíková, Lenka (referee) ; Omelková, Jiřina (advisor)
This thesis describes properties and utilization and specifies the composition of organic plant waste produced during industrial processing. By cultivation of specific micro-organisms from this waste material it is possible to produce enzymes that have further beneficial industrial utilization. The experimental part of this thesis deals with the production of enzymes from the applied waste material grape pomace with the help of chosen micro-organisms. Waste, its processing and utilization is and always will be a key issue in our society.

Utilization of biomass for the energy purposes
Romanová, Kristýna ; Ing.Ondřej Kosík, Ph.D. (referee) ; Flodrová, Dana (advisor)
The theoretical part of work focuses on the issue of biomass used for energy purposes, in particular agricultural waste, which can be used as a substrate for biogas station. Furthermore, examines the composition of polymer substrates, which affects most biogas process. The aim of this work was to measure each sample of enzyme activity of biomass, which is used as a raw material for biogas plants.

Manipulator of pack
Raba, Milan ; Čermák, Jan (referee) ; Brandejs, Jan (advisor)
This work is about construcion of a manipulator to be used in paper manufacturing. The manipulator is desinged to turn a package of cellulose placed on a roller conveyor. Turning of the package is necessary for unwrapping and cleaness control of cellulose. Design was made based on analytical calculation and was verified using computer simulation. Pneumatic valves and an electric motor were utilized in the manipulator. The manipulator operates automatically.

Plants polysaccharides and their importance in food production
Klanicová, Barbora ; Illková, Kateřina (referee) ; Omelková, Jiřina (advisor)
Some findings about plant polysaccharides, their characteristics and structures, modifications, changes, their biosynthases, isolationes and primarily their importance in food-stuff industry are the subject matter of this review. Because of their modifications and because of the significant role they play in food-processing industry it is focused on starch and cellulose. For better understanding of whole meaning it was necessary to attend to the theme from the initiation – mainly the cell structure and then syntheses, especially photosynthesis, ways that are monosaccharides and polysaccharides generated.

Ecological roles of bacteria associated with plant litter
Tláskal, Vojtěch ; Baldrian, Petr (advisor) ; Seydlová, Gabriela (referee)
Leaf litter in temperate forests represents an important input of carbon into the soil. Main players in the decomposition of leaf litter are fungi and bacteria. While the role of fungi in litter decomposition was repeatedly addressed, there are just a few field studies where litter-associated bacteria were also considered. The aim of this work was to summarize available literature studying the structure and function of bacterial community during litter degradation. The nature of different possible substrates is discussed. Genetic approach is briefly outlined. Factors such as diversity, spatially distribution and abiotic factors that can influence community are also considered. It can be supposed that community composition changes with the change of litter chemistry and nutrient availability. The development of bacterial community might be driven by the decreasing availability of nutrients in litter. Labile compounds are utilised at the beginning of decomposition, while recalcitrant substrates are utilised later by specialist taxa. Members of the phyla Actinobacteria, Acidobacteria, Bacteroidetes and Proteobacteria seem to be dominant during decomposition. Different types of relationships between fungi and bacteria also most likely influence the composition of community. This review shows that the bacterial...
