Phenol Red Broth Medium is formulated as per Vera. It is a recommended medium used to determine the fermentation reaction of carbohydrates for the differentiation of microorganisms. Phenol Red Broth Medium with various carbohydrates serves as a differential medium by aiding in differentiation of various species and genera by their ability to ferment the specific carbohydrate, with the production of acid or acid and gas. Proteose peptone and beef extract serve as sources for carbon and nitrogen. Sodium chloride is the osmotic stabilizer. Phenol red is the pH indicator, which turns yellow at acidic pH i.e. on fermentation of dextrose. Gas formation is seen in Durhams tubes. All species of Enterobacteriaceae grow well in this medium. In addition to producing a pH colour shift, the production of mixed acids (notably butyric acids), often results in a pungent, foul odour emanating from the culture medium.
