During urease production testing, ammonia reacts to form which of the following products?

During urease production testing, ammonia reacts to form which of the following products?

• A. Ammonium citrate
• B. Ammonium carbonate
• C. Ammonium oxalate
• D. Ammonium nitrate

Answer: (B)

Urease production testing primarily involves the hydrolysis of urea into ammonia and carbon dioxide by urease-producing bacteria. When ammonia is produced, it can react with carbon dioxide in the presence of water, leading to the formation of ammonium carbonate. This product is indicative of the urease activity, as the alkaline conditions created by ammonia can be detected by a color change in the medium used for the test. Ammonium carbonate forms due to the combination of ammonia (NH3) and carbon dioxide (CO2), which occurs during this metabolic process. The other products listed do not form as a result of urease activity. For example, ammonium citrate is associated with citric acid metabolism, ammonium oxalate is connected to oxalic acid metabolism, and ammonium nitrate involves a different biochemical process often related to nitrogen fixation rather than urease activity.
