摘要
对10株乳酸菌进行了体外抑菌试验,发现乳酸菌对革兰阳性和革兰阴性指示菌均有明显的抑制作用。10株乳酸菌中X1、LM1、C15三株细菌的抑菌效果最好。选择X1、C15两株细菌进行细菌素的提取以及用SDS-聚丙烯酰胺凝胶电泳方法进行初步鉴定,发现有明显的电泳条带。
An bacteriostatic experiment of 10 LAB isolated from silage was conducted. The results showed that LAB not only could inhibit the Gram-positive bacteria, but also inhibit the Gram-negative bacteria obviously. X1, LM1 and C15 of 10 LAB had better inhibiting effects than others. X1 and C15 were selected to extract the bacteriocin and proved their existence with SDS-PAGE.
