MINERAL MODIFIED GLUTAMATE AGAR BASE (DOUBLE PACK) (ISO 6391:1997)

Description

Folpmers described a glutamic acid based chemically defined medium for the enumeration of coliform bacteria from water and wastewater. This glutamate-containing medium was later modified by Gray, by the addition of lactose, which gave less false positive results when compared to MacConkey Broth. Mineral Modified Glutamate Agar Base is recommended for the enumeration of Escherichia coli from meat and meat products by colony count at 44?C by membrane filtration technique. Anderson and Baird-Parker described a direct plate method for the rapid enumeration of E. coli in foods and this method was modified by a resuscitation procedure using Mineral Modified Glutamate Agar with successful recovery of damaged cells from frozen, dried, heat processed or low pH foods.
