Lipases are widely distributed
in nature and catalyze the hydrolysis of mono, di and tri acyl glycerols to
liberate free fatty acids and glycerol. Various microorganisms produce lipases either
alone or together with esterase. Lipases form an important group of relevant
enzymes and they were used in a variety of biotechnological fields such as food,
pharmaceutical, detergent, textile and cosmetic industries. Lipases from lactic
acid bacteria may contribute in the development of flavors in foods especially
meat products. The goal of the present study is to investigate the ability to
produce lipolytic enzymes lactic acid bacteria strains which is selected as
potential probiotics and isolated on pastırma samples in our laboratory to
determinate the possibilities of using as starter cultures in pastırma
production. Lipolytic activity of lactic acid bacteria isolated from pastırma has
not been investigated up to now. The plate assay is performed to screening
lipolytic activity of lactic acid bacteria isolates. In the study, 3 different growth
medium tried and each medium contain tributyrin as a substrate. Using these
methods, 50 strains of lactic acid bacteria isolated from Turkish pastırma are
screened for the presence of lipolytic activity. As a result of the
analysis, the lipolytic activity is observed in 26 tested strains. Lactobacillus plantarum have highest
lipolytic activity.
