	Organical chemicals from biomass DOLEŽAL, David This bachelor thesis deals with the processes of biomass as a renewable resource for the production of chemicals that could compete chemicals obtainable from fossil sources. Processing of biomass can be divided into two main approaches namely a thermochemical and biotechnological processing of biomass processes. This processing involves many processes such as hydrolysis, crushing, fermentation, combustion or high temperatures and pressures, and many other thermochemical or biotechnological processes associated with the nature of the structure of the biomass. As the most important products of biomass processing can be considered biofuels represented in my work mainly by ethanol, but also methanol and other organic chemicals such as furfural, levulinic acid and hydroxymethylfurfural derived from the processing of C5 and C6 sugars located in the fundamental structure of biomass. These organic chemicals can also serve as a chemical platform and subsequent modifications of them can get products with the same or very similar properties of the products of the petrochemical industry.

	Factors influencing quality and nutritive value of grass silages NOVOTNÝ, Jaroslav The paper analyzes the factors affecting the quality and nutritive value of wilted grasssilage. Grass silage sample were collected in the operating conditions for the firstmowing. Three groups were formed after 12 samples. The first group was the controlwithout using preservatives. The sekond group were included in the silage treated withbacterial agents. The third group included the bacterial-enzymetreated silage additives. There were no statistically signifiant differences in lactic acid kontent (P < 0.05) andvalues of thedegree of proteolysis (P < 0.05) between the kontrol group without the useof silage additives and the group, which was used for bacterial and bacterial-enzyme additives.
