Mikrobiální lipázy a jejich využití / Microbial lipases and their application

This diploma thesis is focused on the study of the preparation for fat separators and wastewater pipes that contains the microorganisms with lipolytic activity. Theoretical part of this thesis describes lipases, microorganisms producing this enzymes and usage of lipases. In this part possibilities of identification of microorganisms are presented too. The practical part is concerned with the study of commercial preparation Sany Duo Spezial with proven presence of microorganisms with lipolytic activity. These microorganisms were identified by means of the PCR method. This method identified mictoorganisms like genus Bacillus sp. Next characterization of the preparation was focused on the determination of COD and the investigation of the influence of various conditions of culture medium on the lipases production and their activity. The effect of temperature, ions and pH was studied. Lipolytic activity was determine spectrophotometricaly with usage of p-nitrophenyllaurate whitch dissociates to yellow product p-nitrophenol.
