摘要
根据对优良益生菌的要求,从健康乳猪肠道中分离筛选到13株乳杆菌,其中嗜酸乳杆菌3株、干酪乳杆菌1株、链状乳杆菌1株、发酵乳杆菌8株。所选菌株能耐受1.0％的牛胆盐,对 pH3.0的酸度有较强的抵抗力,并能抑制常见致病菌,对小白鼠安全无毒,是制备益生素的优良菌种。
According to the requirements of ptobiotics, we have separated 13 strains of Lactobacillus from the content in gut of lactating piglet. Among them 3strains are L. acidophilus, one is L. casei, one is L. atenaforme and 8 strains are L. fermentum. They can resist 1.0% bile salt and the acidity of pH3.0, can inhibit pathogenic Escherichia coli and Staphylococcus aureus. They are safe and non-toxic to mice.
