This work deals with the problem of microbial degradation of the waste materials from food industry. This work is focused on the production of technological significant enzymes producing by microorganisms, which were able to use the waste as a sole carbon source. In the first part of this work, the attention was focused on the production of pectolytic enzymes. This part was made within study interships in Slovak Academy of Sciences, department of Glycomics in Bratislava. The grape pomace as the waste form winegrowing was used as a sole carbon source for microbial growth and enzymes production. The production of pectolytic enzymes was tested on this waste. After screening the most suitable microorganisms was chosen with the highest production of polygalacturonase activity. Produced enzymes were isolated by extraction techniques, purified and then identified proteomically. The aim of the second part of this work was the waste water treatment containing lipids and lipolytic enzymes. The reason was the cooperation with the company constructing grease traps. The characterization of supplied commercial preparations was the subject of this work and the other reason was the characterization of conditions for lipases secreting by microorganisms, identification of microorganisms present in the commercial preparation and testing of new microbial cultures for the development of new preparation for the grease traps.
