目前,纯净水和饮水机已走入家庭、办公室和学校中,能否饮用上真正安全合格的水已成为人们生活中的焦点问题。为此,我们根据微生物学实验方法,设计了实验方案,测定水样细菌总数是否符合饮用水标准。 实验方法:制备普通牛肉膏蛋白胨琼脂培养基,使水样与培养基充分混合后,在一 At present, pure water and drinking fountains have entered homes, offices and schools. The ability to drink truly safe water has become a focal issue in people’s lives. To this end, we designed an experimental protocol based on microbiological experimental methods to determine whether the total number of water-borne bacteria meets the drinking water standard. Experimental method: Preparation of an ordinary beef extract peptone agar medium, after the water sample and the culture medium are fully mixed, in one
