[Abstract]  Here we describe a protocol which we have used to study the homeostasis intracellular in vivo in lactic acid bacteria (LAB) using a fluorescent probe. This type of probes can be used for determining changes in the pH of cytoplasm with high sensitivity, temporal resolution and technical simplicity as well as accessing the rate of change of intracellular pH in response to a stimulus from kinetic measurements on short time scales (Breeuwer et al., 1996; Molenaar et al., 1991). This protocol has been designed to measure the intracellular pH using the pH-sensitive ... [摘要]  在这里我们描述了一个协议,我们已经用来研究乳酸细菌(LAB)使用荧光探针在体内细胞内体内平衡。 这种类型的探针可用于以高灵敏度,时间分辨率和技术简单性确定细胞质pH的变化,以及响应于来自短时间尺度上的动力学测量的刺激,获得细胞内pH的变化速率(Breeuwer& et al。,1996; Molenaar et al。,1991)。 该方案已经设计为使用pH敏感性荧光探针在LAB中的2'-,7'-双 - (2-羧乙基)-5(和-6) - 羧基荧光素(BCECF),粪肠球菌 ( E.cfaecalis ),乳酸乳球菌(<乳酸乳球菌)和干酪乳杆菌 em=""> L。casei )。
