If you are referring to media for the isolation of nitrifying 
bacteria, phenol red is used only as a visual means of assessing pH.  
While pH meters are available, its a pain to have to use them whenever 
you are concerned about pH.  An experienced technologist can look at a 
solution of containing phenol red and know if the pH needs to be 
adjusted.  We routinely use phenol red in tissue culture media for the 
same reason.  It just saves time, and is more convenient.
