Simmons Citrate Agar

Product information

A medium devised by Simmons in 1926 to help in the differentiation of enteric bacteria and in the isolation of fungi. Certain Enterobacteriacae have the ability to utilize citrate as the sole source of carbon and utilize inorganic ammonium salts as the sole source of nitrogen resulting in an increase in alkalinity. Bromothymol Blue is used as a pH indicator.
