Yeast Nitrogen Base w/o Amino Acids is used for classifying yeasts based on carbon and nitrogen requirements and is prepared according to the formulas of Wickerharm and Burkholder. The medium contains all the essential vitamins and inorganic salts needed to cultivate yeasts, except for the amino acids and carbohydrate sources. Ammonium sulphate is included as a readily available nitrogen source for nitrogen assimilation.
This medium is used in many applications for the study of yeast in molecular biology as is useful for the determination of aminoacids and carbohydrate
utilization.
