About this item
Urea Agar is a differential medium for members of the Enterobacteriaceae on the basis of their ability to produce urease.
- Peptone and dextrose provide nutrients
- Reduced buffer content helps promote rapid growth
- Utilized urea produces ammonia
When organisms utilize urea, ammonia is formed during incubation, which makes the reaction of these media alkaline, producing a pink-red color. Consequently, urease production may be detected by the change in the phenol red indicator.
