HiCromeâ„¢ M-TEC HiCynthâ„¢ Broth 100G

This is a chromogenic media used for detection and enumeration of thermotolerant Escherichia coli(TEC) in water by membrane filtration. The medium contains the chromogen, 5-bromo-6-chloro-3-indolyl-b-D-glucuronide that is cleaved by enzyme ß-D-glucuronidase to yield glucuronic acid, produced by Escherichia coli strains. This imparts a purple-magenta colour to the colonies of Escherichia coli only.
