Descrição

Descrição geral

Plate Count Agar is the recommended medium forthe isolation of microorganisms in milk and other dairy products. The enzymaticdigest of casein (tryptone) with a high level of free amino acids is a nitrogensource. Yeast extract primarily supplies the B-complex vitamins. Glucose is anenergy source for the growth of bacteria, while agar is the solidifying agent.Plate Count Agar is also suitable for determining bacterial count from sterilerooms.

Aplicação

Plate Count Agar is a non-selective medium for the plate count of microorganisms in water, food, milk, dairy products, beverages, animal feed, and other materials.
