The biochemical pathway that the methyl red test confirms is:
A) Glucose ® pyruvic acid ® mixed acid fermentation
B) Pyruvic acid ® glucose ® mixed acid fermentation
C) Glucose ® pyruvic acid ® acetoin ® diacetyl KOH
D) Butylene ® pyruvic acid ® diacetyl KOH

Question

Quizplus · Accepted Answer

Bacteria are incubated in a media containing glucose.The bacteria utilize the glucose via the Embden-Meyerhof pathway.The end product of this pathway is pyruvic acid.Bacteria continue to oxidize the pyruvic acid into a variety of other acids.An indicator is added to the broth that will turn deep red if it is at a low pH.
