MINERALS MODIFIED GLUTAMATE BROTH 500 grams/bottle

Minerals Modified Glutamate Broth (MMBG) ISO is recommended by ISO 16649-3 for enumeration of E.coli using the most probable number Method (MPN). MMGB Broth is also an alternative broth used for the presumptive identification of coliforms in water. In comparison to other media, this broth is better as it gives fewer false positive results. Sodium glutamate and sodium formate are the basis of the medium for the enumeration of coliform organisms in water. Lactose is the source of carbohydrates. The addition of vitamins, aminoacids and heptahydrate magnesium sulfate increase fermentation, whereas the addition of ferric ammonium citrate permits increase of gas production. The bromocresol purple is a pH indicator.
