A selective medium, blood-glucose-liver agar containing oxgall (.2 mg/ml) and gentamicin (30 micrograms/ml), was formulated for the selective enumeration of bifidobacteria in fermented dairy products containing both lactobacilli and streptococci. Recovery rates of bifidobacteria on this selective medium were around 90% of recovery on blood-glucose-liver agar. Strains of lactobacilli and streptococci were mostly inhibited with higher dilutions on this selective medium.
一种选择性培养基，即含有牛胆汁（0.2毫克/毫升）和庆大霉素（30微克/毫升）的血糖-肝脏琼脂培养基，被配制用于在同时含有乳酸菌和链球菌的发酵乳制品中选择性计数双歧杆菌。双歧杆菌在这种选择性培养基上的回收率约为在血糖-肝脏琼脂培养基上回收率的90%。乳酸菌和链球菌菌株在这种选择性培养基上大多被更高的稀释度所抑制。
