Simon's citrate medium

Simon's citrate medium

Simon's citrate medium is a basic biochemical identification medium for identifying whether bacteria can use citrate as the only carbon source. Its composition takes sodium citrate as the sole carbon source, ammonium dihydrogen phosphate as the nitrogen source, and contains inorganic salts such as sodium chloride and magnesium sulfate, and bromothymol blue as the acid-base indicator. When some bacteria (such as some Enterobacteriaceae bacteria) can use citrate, they will decompose ammonium salt to produce alkali, which will increase the pH of the culture medium and change the indicator from green to dark blue, which is a positive reaction. This test is a key index in microbial classification and identification, especially in Enterobacteriaceae identification.
