Principle
- MGYP agar with copper is used for testing the quality of beers in the Brewing industries. MGYP agar with copper is composed of yeast extract, malt extract, malt extract, gelatin peptone, dextrose, cupric sulphate and agar.
- The media is formulated to enumerate the wild yeasts and bacterial contamination in the brewing industry.
- The wild yeast and bacterial contamination are easily differentiated on the basis of morphological features. Yeast extract and Malt extract provide necessary nutrients to support the growth of yeasts.
- Dextrose is the carbon source for the growth of yeasts. Gelatin peptone is the source of nitrogen.
- Cupric sulphate is used to inhibit the growth of larger yeast. The acidic pH in the medium inhibits the growth of bacteria and favours the growth of yeasts.
