The employment of wastes from food production
 Hurčíková, Andrea ; Babák, Libor (referee) ; Omelková, Jiřina (advisor)
The waste from agricultural and food industry are accessible in large quantity anywhere in the whole world nowadays. Most of these wastes include cellulose (30 - 40 %), hemicellulose (20 - 40 %) and lignine (10 - 20 %). Therefore these waste materials have wide use as the substrates for the microbial growth and the production of the enzymes. The microorganisms are able to use organic compounds from the wastes as the source of energy for the growth and carbon for synthesis of cellular biomass [24]. Wheat and rice straw are possible to use as the substrates for cultivation of the microorganisms and following production of the enzymes. In this thesis the utilization of the wastes from food industry for the production of the enzymes by the microorganisms was studied. We observed utilization of wheat straw as source of energy for growth of tested microorganisms and investigated their ability for the production of oxidoreductase (laccase). The optimalization of growth conditions of Aureobasidium pullulans was proceeded. Further the activity of laccase was studied. Milled wheat straw was used as the substrate. The cultivation was done in the thermoregulator at the temperature of 27°C. The activity of laccase was not found in this thesis. Petri dishes were contaminated by three unknown microoganisms during optimalization of growth of Aureobasidium pullulans. One of them produced laccase in cultivation with straw.

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.
