Updated On: May 5, 2025
- Enterobacter aerogenes
- Escherichia coli
- Aspergillus niger
- Klebsiella pneumoniae
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The methyl red test detects the ability of bacteria to ferment glucose and produce stable acids. Enterobacter aerogenes gives a negative result, but Escherichia coli and other bacteria can give a positive result, indicating mixed acid fermentation.
