Phenol Red Broth Base w/ Meat Extract

(Revised as Phenol Red Broth Base w/ HM Peptone)

Phenol Red Broth Base with Meat Extract is a highly nutritive basal medium used to study carbohydrate fermentation.
This medium does not contain added carbohydrates, allowing users to supplement specific carbohydrates for determining fermentation reactions of pure microbial cultures.

It can also serve as a negative control in fermentation studies that produce acid and gas, aiding in differentiation between genera and species.

• Positive reaction: Medium turns yellow due to acid production, indicated by phenol red, a pH indicator.
• Gas production: Formation of bubbles trapped in Durham’s tube.
