摘　　要：研究了菌株间的差异,通过改变现有商业培养基的培养条件,如培养温度、时间、pH、添加不同的抗生素等,共选择12种培养基对保加利亚乳杆菌、嗜热链球菌、嗜酸乳杆菌等12株发酵菌种进行了选择性的计数。As of recent, uniform standard methods for selective enumeration of dairy culture strains is not available. The differences between strains were studied. By improving culture conditions, for example incubation temperature, time, pH value, and adding different antibiotics, 12 commercial media were selected for selective enumeration of 12 dairy culture strains, including Lactobacillus bulgaricus, Streptococcus thermophilus , Lactobacillus acidophilus.
