Glucose Chloramphenicol Agar is recommended by the International Dairy Federation (FIL-IDF) for the isolation and enumeration of yeasts and moulds in milk and dairy products. Yeast extract is the water-soluble portion of hydrolysed yeast and is a source of vitamins, particularly of the B-group, and other growth nutrients that stimulate yeast and mould development. Glucose is the fermentable carbohydrate as a carbon and energy source. Chloramphenicol is an antibiotic that helps in isolating pathogenic fungi from heavily contaminated material, as it inhibits most contaminating bacteria. It is a recommended antibiotic for use with media due to its heat stability and wide bacterial spectrum. Bacteriological agar is the solidifying agent.
