B. Citrate Test. • This is a test for citrate utilization. Identifies bacteria capable of using citrate as a sole carbon source. • These bacteria produce the enzyme Citrate Permease that works in conjunction with Citrate Lyase to produce the end products • Utilization of citrate involves the breakdown of citrate to oxaloacetate and acetate. Oxaloacetate is in turn broken down to Pyruvate and CO, Utilization of ammonium salts in the medium produces ammonium hydroxide that renders the medium alkaline...
