Mineral Modified Glutamate Medium is used for enumeration of coliforms in water and wastewater samples. Folpmers first described a chemically defined medium based on glutamic acid for enumerating coliforms in water. However in the early days following its discovery, it was seen that the medium containing glucose gave many false positive results in 48 hours.It was then modified by Gray who incorporated formate and lactose in the medium which gave improved performance. This medium can also be used for detecting Escherichia coli in chlorinated waters and is better than Lauryl Tryptose Lactose Broth for the detection of small numbers of Escherichia coli. This medium contains a variety of nutrients including salts, amino acids and vitamins. Lactose is the fermentable carbohydrate and bromo cresol purple is the pH indicator. Because of the nutrients, this medium is superior for enumerating coliforms in water and wastewater as it satisfies most of the nutritional requirements of coliforms.
