These media are used for the differentiation between Enterobacteriaceae and the members of aero genes group on the basis of citrate utilization as sole carbon source. Initially the citrate medium was developed by Koser containing ammonium salt as the only nitrogen source and citrate as the only carbon source for differentiating Escherichia coli and Enterobacter aero genes by IMViC tests. Later on Simmons (2) modified Kosers formulation by adding agar and bromothymol blue (3). It is recommended by APHA (4).It is also recommended by BIS (5) for isolation of Escherichia coli. Ammonium dihydrogen phosphate and sodium citrate serves as the sole nitrogen and carbon source respectively. Bromo thymol blue is the pH indicator. The organisms produce an alkaline reaction which is indicated by the change in color from green to blue.
