Studium přípravků do odlučovačů tuků / Study of preparations for fat separators

Diploma thesis was concentrated at testing of a single commercial product designed as a lipid residue removal agent, applicable in grease trap vessel. Concept was, that product is to be tested for possible content of viable microbial culture with ability to utilize various kinds of vegetable oils and animal fats, by producing functional lipase. Four types of vegetable oils were used, and two fats of animal origin: olive oil, palm oil, rapeseed oil, sunflower oil, lard and beef fat. Determined fat characteristics were: point of the saponification, the acid value, the ester value and the peroxide value. Submerged cultivation was performed on specially composed medium in which the oil or fat of choice, was mixed later. Lipolytic activity and biomass growth measurement was performed using spectrophotometry, lipid degradation ability was measured using titrimetry. Based on results it can be stated that tested microorganisms, originated from product, and its lipase has ability to successfully utilize all of used fats and oils and thus, theoretically, remove its content from grease trap.
