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, is Sim selective or differential? Sulfur Indole Motility Media (SIM) This is a differential medium. It tests the ability of an organism to do several things: reduce sulfur, produce indole and swim through the agar (be motile). SIM is commonly used to differentiate members of Enterobacteriaceae.
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.
What is the citrate utilization test used for?
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.
