MMO-MUG Medium

MMO-MUG Medium is an advanced chromogenic and fluorogenic culture medium designed for rapid detection of total coliforms and Escherichia coli in drinking water, source water, municipal water systems, and environmental water samples. Utilizing proven Defined Substrate Technology (DST), MMO-MUG Medium delivers accurate water quality testing results within 24 hours, making it a preferred solution for water microbiology laboratories and public health monitoring programs.

The formulation contains ONPG and MUG substrates that enable simultaneous identification of coliform bacteria and E. coli. Coliform organisms produce β-galactosidase, which hydrolyzes ONPG and turns the medium yellow, while E. coli produces β-glucuronidase that hydrolyzes MUG, generating fluorescence under 366 nm UV light. This dual-indicator technology supports rapid microbial contamination detection, drinking water analysis, regulatory compliance testing, and environmental monitoring.

MMO-MUG Medium is widely used for coliform testing, E. coli detection, potable water safety assessment, and microbiological quality control. Manufactured by Babio Biology, a leading Chinese manufacturer of microbiological culture media, this high-performance medium offers reliable results for laboratories worldwide.
