一、计数原理酵母菌是一种在适宜条件下进行出芽生殖的单细胞真核生物,个体较大,能在高倍显微镜下清晰可见。酵母菌的生长周期短,增殖速度快,在实验室条件下,用液体培养基培养酵母菌,可以观察酵母菌种群数量随时间变化的情况。对培养液中的酵母菌逐个计数是非常困难的,可以采用抽样检测法进行估算。利用血球计数板在显微镜下直接进行测 First, the counting principle Yeast is a single cell eukaryotic budding reproductive under appropriate conditions, the individual larger, can be clearly seen under high magnification microscope. Yeast growth cycle is short, rapid proliferation, under laboratory conditions, the use of liquid medium culture of yeast, you can observe the yeast population changes with time. It is very difficult to count the yeast in the culture liquid one by one, and it can be estimated by the sampling method. Measured directly under the microscope using a hemocytometer
