Description

General description

Simmons Citrate Agar uses citric acid as the carbon source. It is used to differentiate Salmonella groups from each other. It does not allow the growth of Shigella or coliforms.

Application

Simmons Citrate Agar can be used for differentiating between fecal coli and members of the aerogenes group based on citrate utilization. It can also be used for the identification of certain fungi and fungi imperfecti. The agar has been used to perform a citrate test.
