Preparation Note

A. Nitrogen Assimilation test
Prepare the broth base at 10 x concentration by dissolving 11.7 grams of Yeast Carbon Base in 100 mL of distilled water. Add the appropriate nitrogen source. Warm if necessary to dissolve the medium completely. Sterilize by filtration.
B. Detection of yeasts, other than Saccharomyces cerevisae
Dissolve 2.35 grams of Yeast Carbon Base in 100 mL of distilled water.
C. Detection of wild yeasts in beer and other brewing components
Add 0.33 g of ammonium sulphate (Catalog No. A2939) and 4 g of bacteriological agar (Catalog No. A5306) to base B. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes.
