EC Blue Comparator    Prodotto

Positive samples in natural light
Coliform bacteria produce the ß-galactosidase enzyme, which then cleaves the synthetic substrate X-GAL contained in the EC Blue and simultaneously releases a blue/blue-green dye.

Positive samples under UV light
About 95 % of all E.coli strains produce the ß-glucuronidase enzyme. This enzyme hydrolyses the MUG enzyme substrate and thus releases a fluorescent dye that can be detected with UV light.
