In present study, the effects of carbon sources (glucose, lactose, sucrose, galactose, maltose and soluble starch) and nitrogen sources (casein peptone, whey protein, soy peptone, yeast, tryptone, beef extract and peptone) on activity of cell envelope proteinases (CEP), specific activity, protein content, OD 600  value and pH in MRS broth fermented by  Lactobacillus plantarum  LP69 were investigated by individual factor experiment. The results indicated that carbon and nitrogen sources have significant influence on the activity of CEP and specific activitys of  L. plantarum  LP69, glucose, maltose, casein peptone and peptone are superior to other selected carbon and nitrogen sources. The optimum concentrations of glucose, maltose, casein peptone and peptone for  L. plantarum  LP69 are 2%, 2%, 1% and 1%; the activity of CEP are 19.52U/mL, 21.13U/mL, 13.49U/mL and 20.61U/mL, respectively.
