功能

• Developed based on the principle of the specific enzyme substrate method, this medium rapidly screens for Escherichia coli and coliform bacteria in water.
• In coliform bacteria, X-GAL is broken down by β-galactosidase, and the culture medium turns blue to blue-green.
• When 4-MUG is decomposed by β-glucuronidase, E. coli emits fluorescence when exposed to UV light.
