CHRISTENSEN CITRATE SULPHITE AGAR, W/ 1.5% AGAR is supplied by TM MEDIA. It is used for dierentiation of enteric bacilli on the basis of citrate utilization and hydrogen sulphide production.Organisms that metabolize citrate as a sole source of carbon cleave citrate to oxaloacetate and acetate via the citritase enzyme. Another enzyme, oxaloacetate decarboxylase, then converts oxaloacetate to pyruvate and CO2. Further, this CO2 combines with sodium and water to form sodium carbonate, an alkaline compound. As a result, the pH of medium rises and the indicator, phenol red changes from orange red to cerise. Presence of the cerise colour indicates a positive finding for citrate utilization.
