Voges Proskauer (VP) Test- Principle, Procedure, Results, Uses
Objective of VP Test To differentiate two major types of facultative anaerobic enteric bacteria based on the production of neutral products. Principle of VP Test Voges Proskauer test, commonly known as VP test is used to determine the ability of some organisms to produce neutral end products (e.g., 2, 3-butanediol, or acetoin) from glucose fermentation. All members of the Enterobacteriaceae can convert glucose to pyruvic acid by the Embden-Meyerhof pathway, but bacteria can further metabolize pyruvic acid by two different pathways. … Read more
