Calcium Carbonate Agar 500G

Calcium Carbonate Agar is recommended for the differentiation of microorganisms especially yeasts based on the production of acid from glucose.This medium is differentiation agar recommended by Kurtzman and Fell for the identification of yeasts. Calcium carbonate serves as indicator as it makes the plate milky and turbid and in case of acid is produced the media clears up. The acid is produced due to characteristic fermentation of glucose, which along with calcium carbonate results in forming, calcium acetate, that gets soluble in water.
