Is Simmons citrate agar selective or differential?
Also to know is, why is the citrate test selective?
The citrate utilization test is selective because only certain bacteria can utilize citrate in place of a fermentable carbohydrate.
Also question is, what type of media is the Simmons citrate agar?
Simmons Citrate Agar is an agar medium used for the differentiation of Enterobacteriaceae based on the utilization of citrate as the sole source of carbon. In the early 1920s, Koser developed a liquid medium formulation for the differentiation of fecal coliforms from the coliform group.
Citrate utlilization test is used to determine the ability of bacteria to utilize sodium citrate as its only carbon source and inorganic ammonium dihydrogen phosphate (NH4H2PO4) is the sole fixed nitrogen source.
