Coloring Principle
Coliforms positive
There is a special β-galactosidase only exit in the coliforms. It can be used as an indicator enzyme for coliform bacteria, which catalyzes the hydrolysis of the substrate X-GAL to form 5,5-dibromo -4,4-dichloro indigo, appearing light blue ~ purple-blue.
β--glucuronidase can be used as an indicator enzyme for Escherichia coli; because β-glucuronidase can be observed in Escherichia coli, Salmonella and Shigella in intestinal bacteria, and 95% of E. coli contains β-glucuronidase. It catalyzes the hydrolysis of MUG to form 4-methylumbelliferon, which exhibits fluorescence at 366 nm ultraviolet light and is visually discernible under indoor light intensity.
In the case of neutralization of disinfectants such as quaternary ammonium is quite important to the antimicrobial activity, it is recommended to use Letheen Broth of Swab Samplerto test preservative materials.
