Environmental load during production a processing of food wheat and production of bread
HYŠPLER, Robin
This thesis was made in co-operation with international project M00080- EUS-AT-SUKI Sustainable Kitchen, which is focused to make an inquiry of total emissions of carbon dioxide producted by catering estabilishments and finds possibilities of reducing these emissions. The thesis deals with an emission?s contamination of wheat flour and bread. Informations and data about agriculture, processing and transport of chosen commodities were collected from questionaires and scientific literature. The emission?s contamination of equivalent CO2 per kilogram of particular products and commodities was worked out from data and informations of the Ecoinvent database. The comparision between systems of management and regionality (ie. whether products are imported or local) is included. The main aim of this thesis was to prove whether the consumation of products from organic or conventional farming is environmentally more beneficial, the same comparision were made between regional or imported products

Alcohol Yield of Oat, Barley and Wheat Hydrolysates
PIKL, Miroslav
Major part of ethanol production for industrial use in Czech Republic is made from cereals. Effect of acid, alkali and enzymatic hydrolysis after thermopressure preparation takes part in the paper. The most promising alternative is enzymatic hydrolysis. Especially efficiency of different hydrolytic enzymes towards different species of cereals takes the main part of the simulations. Local farm products, oats, barley and wheat were prepaired by steam explosion in different pressure. After hydrolysis were detected the GE and after fermentation was observed the production of alcohol.

Seeds surface plasma modification
HRUŠKOVÁ, Iveta
Aim of diploma work is research of plasma influence on seed germination in some plant species (wheat and oat). The complex work includes parts both physical-technological and biological. The work discusses a selection of useful seeds for the plasma treatment and describes parameters of plasma processing. It discusses results of germination testing and early growth of seedlings. Parts of the work are electron microscopy output, data processing result, and appendix.

The issue of microscopic fungi in wheat
HORMANDLOVÁ, Jana
The aim of my thesis was to monitor the natural occurrence of mycological pathogens, especially funghi of genus Fusarium in ecologically and conventionally grown systems. There was carried out small-parcelled experiments at two standpoints (Lukavec and České Budějovice) in the years 2006/2007, 2007/2008 and 2008/2009. The funghi of genus Fisarium attack the stalk, the leaves even the ear. If the ear is attacked, the production is decreased. The epidemical occurrence of this disease is supported by a large amount of cereals in the cropping pattern, nitrogen over-fertilization, thick grassland and bad agro technological proceeding, especially imperfectly nested plant remains. The genus Fisarium is very extensive in the nature. It often parasites at plants or live saprophyticly at production, post-production remains of plants in soil or at its surface. The mycelium furcates and forms cottonwoolen pinkish, red or yellowish film. Their malignity lies with the production of poisonous mycotoxins, which form as their secondary metabolites. They can cause the health problems at people and farm animals.
