Abstract: A novel strain of Lactobacillus zeae RMK354 is provided to improve milk coagulation activity and ACE(angiotensin converting enzyme) inhibitory activity as compared to conventional lactic acid bacteria, so that the strain is suitable for production of functional fermented milk. A novel strain of Lactobacillus zeae RMK354(KACC 91314P) showing improved milk coagulation activity and ACE inhibitory activity is isolated from raw milk by culturing the raw milk in modified MRS(Modified Rogosa SL) medium, isolating yellow colonies as lactic acid bacteria, selecting skim milk-coagulating strains, and selecting a strain showing excellent ACE inhibitory activity from the selected skim milk-coagulating strains, shows optimal temperature of 40 deg. C and needs 10 hours until a pH reaches 4.3 to 4.4 which is optimal pH of fermented milk.
