Describe about pH indicating plates?..

Answer / Tulika Chatterjee

pH Indicating Plates are culture media that contain an indicator such as bromothymol blue or phenol red, which changes color in response to changes in pH. These plates are used for the qualitative detection of microorganisms capable of producing acid or base during their metabolism. The color change helps determine the optimum growth conditions (acidic or alkaline) for certain types of bacteria.
