Some lactic acid bacteria (LAB) strains have been isolated from spontaneously fermented soymilk which showing proteolytic activity. These isolated were expected could producing bioactive peptides that could lowering cholesterol content when they used for soymilk fermentation. This research was aimed to determine the proteolytic activity of Lactobacillus plantarum 1 R.1.3.2 and L plantarum 1 R.1…
