Question

Methyl Red shared the same medium as?

A) Citrate test
B) Urea test
C) Indole test
D) Voges-Proskauer test

Answer 1

Methyl Red shares the same medium as the Voges-Proskauer (VP) test. The medium used for both tests is MR-VP broth, which contains glucose as a fermentable substrate.

Step-by-step explanation:

Methyl Red is a pH indicator used to detect the presence of strong acidic end products in bacterial fermentation. It is commonly used in the Methyl Red (MR) test, which is part of the Methyl Red-Voges-Proskauer (MR-VP) test. This test helps to differentiate bacteria based on their ability to produce acidic end products during glucose fermentation. The MR test shares the same medium as the Voges-Proskauer (VP) test, which measures the production of acetoin, a neutral end product of glucose fermentation. The medium used for both tests, MR-VP broth, contains glucose as a fermentable substrate.
