陕西程控定量封口机的工作原理是什么?价格一台多钱

- 2019-10-25-

程控定量封口机工作原理: 加入含有总大肠菌群细菌的水样,目标细菌在Minimal Medium ONPG-MUG培养基中36℃±1℃培养,总大肠菌群细菌产生的特异性生物酶β一半乳糖苷酶能分解Minimal Medium ONPG-MUG培养基中的色源底物ONPG,使培养呈现黄色;同时水样中大肠埃希氏菌产生特异性的β一葡萄糖醛酸酶分解Minimal Medium ONPG-MUG培养基中的荧光底物MUG,产生特征性荧光。同样原理,耐热大肠菌群(粪大肠菌群)在44.5℃培养时会分解Minimal Medium ONPG-MUG培养基中的色源底物ONPG,使培养基呈现黄色。
