Abstract:
Lactic acid bacteria (LAB) have been demonstrated to have roles in many applications, ranging from lowering of cholesterol to immunological development. In this study, Lactobacillus fermentum was isolated from a new-born's faeces and its genotypic and probiotic characterizations were performed. Our results showed that the survival rate of isolated Lactobacillus fermentum was 39.39% at pH 2 and 81.34% in the stimulated gastric juice at pH 3. It also digested bile salts. Its surface hydrophobicity was found to be 57.59% in n-hexane. These findings indicated that the isolate can be a good probiotic candidate.
