Himedia CPC Agar Base w/ 1% cellobiose

CPC Agar Base w/ 1% cellobiose is used for cultivation and identification of Vibrio species from food in accordance with FDA BAM, 1998. It designed to differentiate Vibrio vulnificus from other Vibrios. Vibrio cholerae strains except V. cholerae 01-classical biotype grow on CPC Agar while most Vibrio parahaemolyticus strains do not grow on CPC Agar. Cellobiose is fermented by some Vibrios producing acid and is indicated by the pH indicator bromothymol blue, which turns yellow at acidic pH. Cresol red is the pH indicator of alkaline range, which turns red at alkaline pH. Alkaline pH of the medium enhances the recovery of Vibrios.
