Industrial production of ethanol
Flajs, Roman ; Zichová, Miroslava (referee) ; Omelková, Jiřina (advisor)
This bachelor thesis deals with ethanol production for food and car industry. The aim of this work is to give a summary of different kinds of raw material especially lignocelluloses and microorganisms used for its processing and fermentation. The thesis focuses especially on technological process of ethanol production and the utilization of different materials for fuel production.

Thermophilic Microorganisms Application for Lignocellulose Materials Biodegradation
Klašková, Lenka ; Zemanová, Jana (referee) ; Babák, Libor (advisor)
The plant cell wall consists of several layers: cellulose, hemicellulose, lignin and pectin. These biopolymers are degraded by many microorganisms. Extracellular enzymes are used for biodegradation by microorganisms. This thesis was focused on studying the impact of cultivation conditions on the production of extracellular enzymes at carboxymethyl cellulase and pectin when a mixed thermophilic culture containing Bacillus and Thermus microorganisms is used. The cultivation was carried out in flasks on a shaking machine with a shaking speed of 99 min-1 at a temperature of 60°C. The monitoring covered cellulolytic and polygalacturonase activities, protein concentration by the Biuret method, concentration of reducing substances by the Somogyi and Nelson methods, and the temperature optimum.
