The determination of bacterial viability in probiotic products is of economic, technological, and clinical significance. We compared four methods to enumerate three Bifidobacterium strains in fermented oat products during storage. A subpopulation of nonculturable cells retained a functional cell membrane typical of viable cells, indicating that probiotic bacteria become dormant during storage.
确定益生菌产品中细菌的活力具有经济、技术和临床意义。我们比较了四种方法，以对发酵燕麦产品在储存期间的三种双歧杆菌菌株进行计数。不可培养细胞的一个亚群保留了活细胞典型的功能性细胞膜，这表明益生菌在储存期间会进入休眠状态。
