Application

Yeast Nitrogen Base Without Amino Acids and Ammonium Sulfate is used in classifying yeasts based on carbon and nitrogen requirements. It contains all essential nutrients required for the growth of yeasts except amino acids, nitrogen and carbohydrate. The addition of nitrogen and carbon sources is required.

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

Yeast Nitrogen Base Without Amino Acids and Ammonium Sulfate is recommended to use for classifying yeasts based on their carbon and nitrogen requirements. The medium contains all essential nutrients required for the growth of yeasts except amino acids, histidine, methionine and tryptophan, and also ammonium sulphate. The addition of nitrogen and carbon sources is required as described in the Manual of Clinical Microbiology

Preparation Note

Prepare a 10× stock solution by suspending 1.7 g of yeast nitrogen base without amino acids and ammonium sulfate in 100 ml of cold distilled water. Include desired nitrogen and carbon sources. Warm if necessary to solubilize and sterilize by filtration. Store 10× stock solution at 2-8°C. To use, dilute 1:10 with sterile distilled water under aspetic conditions.
