Preparation of Medium: Add components to dis
tilled/deionized water and bring volume to 1.0L. Mix
thoroughly. Gently heat and bring to boiling. Dispense
into tubes or flasks. Autoclave for 15 min at 15 psi
pressure–121°C. Pour into sterile Petri dishes or leave
in tubes. Allow tubes to cool in a slanted position.
Use: For the differentiation of enteric pathogens, es
pecially members of the Enterobacteriaceae, and
coliforms based on their ability to utilize citrate as a
carbon source and production of H2S. Bacteria that can
utilize citrate turn the medium pink-red. H2S produc
tion appears as a blackening of the butt of the tube.
