Využití odpadů z potravinářských výrob / The employment of wastes from food production

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.
