Description

Differentiate gram-negative bacteria based on citrate utilization using Simmons Citrate Agar.

Differentiate gram-negative bacteria based on citrate utilization using Thermo Scientific™ Remel™ Simmons Citrate Agar. In 1923, Koser developed a liquid medium to differentiate Escherichia coli and Enterobacter aerogenes1. The medium contained an inorganic ammonium salt and sodium citrate that provided a single nitrogen source and a single carbon source respectively. In 1926, this formulation was modified by Simmons who added 1.5% agar and brom thymol blue indicator2.

Gram-negative bacteria that can utilize ammonium dihydrogen phosphate as a sole nitrogen source and sodium citrate as a sole carbon source will grow on Citrate Agar (Simmons). These organisms extract nitrogen from the ammonium salt by breaking it down
