| Abstract: | In this study, the biological characteristics of 8 strains of Lactobacillus acidophilus isolated from traditional indigenous dairy products were studied. Their growth curve, osmotic pressure tolerance, bile salts to-lerance and antimicrobial activity were analyzed. The results indicated that all the strains could bear 6.0% salt and 1.0% bile salts. The bacteriocins were produced by KLDS1.0365 and KLDS1.0384. |
