To determine if a bacterium can ferment a particular carbohydrate and determine the end products of that fermentation
Yes, but the PH will not fall as low as with the mixed acid route. The PH is an indicator of the route the bacterium used to ferment.

A Link-Pulse indicator
it is an indicator used to determine the distance on a paper and the actual distance on the ground.
The track indicator
it is your fog lamp indicator saying it isn't working properly
The organisms must have been rapicly evolving, widespread, common, and only have been found at a specific strata of geologic time.
Its Ph value is less than 7, so it is acidic. The exact colour change needs to be compared visually with a standard universal indicator chart to determine the precise Ph value associated with that particular shade of red.
they are used to, determine the pH of a solution. ~natalia !
It's called an indicator.
