Diploma thesis was aimed at testing of five commercial products for separators of lipids. Performed study should to shown that in produts are presented lipase-produducing microoganisms, event. that in products are also lipolytics enzymes as addition. The products was cultivated by solid-state and submerged fermentations and subsequently was tested their properties as is lipolytic activity, the amount of free fatty acids etc. Solid-state fermentation used Tributyrin Agar Base where Tributyrin was used as a substrate. Submerged fermentation used special prepared medium where was olive oil. Methods using in this study served for detection and qualification of lipase-produducing microoganisms in individual products. For detection of lipase-produducing bacterial spieces was used Spirit Blue Agar. In this case was used Tributyrin and Tween 80 as a substrate. Lipolytic activity was measured by spectrophotometry and degradation of lipids was measured titrimetry. Performed study demonstrated that all tested products have ability to degradation of lipids.
