Distinguish Escherichia - Enterobacter group using Methyl Red and Voges-Proskauer reactions
Methyl Red test: Differentiate acid producers
Voges-Proskauer reaction: Enterobacter turns red, Escherichia coli does not
وصف
MR/VP broth aids in differentiating enteric Gram-negative bacilli within the Escherichia-Enterobacter group, utilizing the methyl red and Voges-Proskauer reactions. The methyl red test discerns between microbes producing high or low acid concentrations. Enterobacter bacteria, unlike Escherichia coli, oxidize acetylmethylcarbinol, resulting in red coloration.
