Abstract
After screening for the presence of lipase activity in lactobacilli isolated from "chouriço", a traditional Portuguese dry fermented sausage, a strain of Lactobacillus plantarum (DSMZ 12028) was chosen for extracellular lipase characterisation and purification. Proteinase K did not significantly affect lipolytic activity, as opposed to trypsin, which completely eliminated this activity. Among NaCl, Ca2+, EDTA, BSA, glycerol, Mn2+ and Mg2+, only Mn2+ and Mg2+ stimulated the lipase. Purification by gel filtration chromatography and gel electrophoresis revealed four bands, between 98 and 45 kDa, all with lipolytic activity against olive oil.Entities:
