If the organism is able to utilize the carbohydrate, an acid by-product is created, which turns the media … You need to neutralize the chlorine because it will react with the phenol red indicator to create a different compound, chlorophenol red, which behaves differently. If the organism is able to utilize the carbohydrate, an acid by-product is created, which turns the media … Most living tissues prosper at a near-neutral pH; that is, a pH close to 7. Add 3ul to 3ml phenol-red free medium with charcoal stripped FBS, for a final conc. It is purchased as a base broth, which means that NO carbohydrate is in the media. Phenol red is a water soluble dye, named phenolsulfonphthalein, though abbreviated as PSP. The carbohydrate fermentation patterns shown by different organisms are useful in differentiating among bacterial groups or species. That translates to golldurnit, Tiz, All of the PH test reagents manufactured by Taylor, which includes TFTestKits and HTH, have FC neutralizer built-in.
