Product Description
Phenol Red Dulcitol Broth is used for the
determination of fermentation of dulcitol in the
differentiation of microorganisms. The ability of an
organism to ferment a specific carbohydrate in the
basal medium, results in the production of acid and
gas, which helps in the differentiation between the
genera and species of bacteria. Phenol Red Dulcitol
Broth is a complete medium with dulcitol. Proteose
peptone and beef extract provide nitrogenous nutrients
to the organisms. Phenol red is the pH indicator, which
turns yellow at acidic pH. Sodium chloride maintains
osmotic equilibrium. Gas formation is seen in
Durham’s tubes.
