What is Yeast Nitrogen Base?

Yeast Nitrogen Base (YNB) without amino acids is a widely used broth medium for culturing yeasts, particularly for classification based on amino acid and carbohydrate requirements. This medium includes essential vitamins, inorganic salts, and trace elements necessary for yeast growth, except for histidine, methionine, tryptophan, and a carbohydrate source. Its unique formulation makes it an ideal choice for studying yeast metabolism and genetic manipulation.
