Question
What is methyl red test?
 Question Submitted By :: Micro-Biology
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
It is to detect the production of acid during fermentation
of glucose .five drops of 0.04% solution of methyl red are
added to the culture in glucose phosphate medium incubated
at 30 C for five days .red colour is positive and yellow
shows that it is a negative bacteria.

It is used to identify bacteria producing stable acids by
mechanism of mixed acid fermentation of glucose.It is also
used to identify Enteric bacteria based on their patern of
glucose metabolism

Answer
# 5
The methyl red test is the "M" portion of the four IMViC
tests used to characterize enteric bacteria. The methyl red
test is used to identify enteric bacteria based on their
pattern of glucose metabolism. All enterics initially
produce pyruvic acid from glucose metabolism. Some enteric
subsequently use the mixed acid pathway to metabolize
pyruvic acid to other acids, such as lactic, acetic, and
formic acids. These bacteria are called methyl-red positive
and include Escherichia coli and Proteus vulgaris. Other
enterics subsequently use the buytylene glycol pathway to
metabolize pyruvic acid to neutral end-products. These
bacteria are called methyl-red-negative and include
Serratia marcescens and Enterobacter aerogenes
