Methyl Red Voges
Methyl Red Voges-Proskauer Test
Questions
A.What is meant by the term biochemical profile?
Biochemical profile is a variety of biochemical tests. These various tests are used to measure the constituents of plasma and serum in blood.
B.What metabolic end product does the MR test for?
The metabolic end product MR tests for are the different bacteria’s related to their individual patterns of glucose metabolism.
C.What does an orange color indicate as a result for an MR test?
An orange color as a result on an MR test indicates an inconclusive result, neither a positive or negative result.
D.What metabolic end product does the VP test for?
The metabolic end product VP tests for is the presence of acetylmethylcarbinol, also known as acetoin.
E.Why do you need to be careful not to jostle the VP tube while waiting for the results to show?
You need to be careful not to jostle the VP tube while waiting for the results to show because it can interfere with the process that is taking place and alter the end result.
F.Which of the organisms, if any, fermented glucose?
Both E. coli and S. epidermidis fermented glucose.
G.Which of the organisms, if any, produced measurable acidic byproducts?
Both E. coli and S. epidermidis produced measurable acidic byproduct.
H.What is the cellular role of catalase?
The cellular role of a catalase is to enable the breakdown of hydrogen peroxide into water and molecular oxygen.
I.Which of the organisms, if any, produced catalase?
S. epidermidis is the organism that produced catalase.
J.Which of the organisms, if any, produced acetoin
S. epidermidis is the organism that produced acetoin.
