摘要
保加利亚乳杆菌和嗜热链球菌有共生关系,较难分离。根据保加利亚乳杆菌和嗜热链球菌对培养基pH值的不同需求,分别配制不同的培养基,将其分离开来;然后将保加利亚乳杆菌和嗜热链球菌活化菌悬液以(1~2)∶1的比例混合,制得一种优良的酸奶发酵剂。
Because of symbiosis relation between Lactobacillus bulgaricus and Streptococcus thermothillus, it is difficult to separate them. According to the different demand on pH value,Lactobacillus bulgaricus and Streptococcus thermothillus were separated by different media,and then a excellent yogurt fermentation agent was prepared by mixed Lactobacillus bulgaricus and Streptococcus thermothillus with ratio of (1-2): 1.
