| Application: | 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. |
| Footnote: | We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs. The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance. |
| General description: | 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. |
