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.
乳酸菌（LAB）已被证明在许多应用中具有作用，范围从降低胆固醇到免疫发育。在这项研究中，从新生儿的粪便中分离出发酵乳杆菌，并对其基因型和益生菌特性进行了研究。我们的结果表明，分离出的发酵乳杆菌在 pH2 下的存活率为 39.39%，在 pH3 的刺激胃液中的存活率为 81.34%。它还能消化胆盐。其在正己烷中的表面疏水性为 57.59%。这些发现表明，该分离株可能是一种良好的益生菌候选株。
