What Is The Purpose Of Phenol Red In The Carbohydrate Fermentation Test at Joseph Sauls blog

What Is The Purpose Of Phenol Red In The Carbohydrate Fermentation Test. What is the purpose of the phenol red in the carbohydrate fermentation broth? Durham tubes are inserted upside down in the test tubes to detect gas production. We will use phenol red as the ph indicator. If the fermentation test is being done to test fermentation of lactose, lactose is added to phenol red medium and the medium is called phenol. During fermentation most bacteria convert carbohydrates into organic acids, with or without the production of gas. The phenol red is the ph indicator in the experiment. In the phenol red peptone broth test, media containing a given carbohydrate, a ph indicator, and an ‘upside down test tube’, i.e., the durham tube, will be inoculated and Carbohydrate fermentation test is used to assess the ability of bacteria to ferment a specific carbohydrate and to differentiate bacteria based on their carbohydrate fermentation pattern and identify them. Other ph indicators such as bromocresol/bromocresol purple (bcp), bromothymol/bromothymol blue (btb), and andrade’s can be used. Phenol red is commonly used as a ph indicator in carbohydrate fermentation tests. One can test for this by adding a ph indicator and an inverted tube (a durham tube) to the culture medium. Acid end products from carbohydrate fermentation lower the ph causing the ph indicator phenol red to turn from red (neutral) to yellow (acid), but there is no gas bubble seen at.
